As most folk around me, I was bothered by the different video formats.I have differently formatted files stored in you PC,and not every palyer support all the formats.So I afford nearlly all of my day online for the answer,and hope my pleasant can share with those who cannot distinguish the diverse video formats. Video formats are classified into two applications, one for local use and the other for Internet. The formats for local use include AVI, nAVI, WMA,MPEG suite, RM,MOV, etc. What the differences between these formats? The AVI (Audio Video Interleave) format was developed by Microsoft. AVI has such advantages as high image quality, application in multi-platforms. But its disadvantages are also explicit, large volume, without a unified compression standard, and the most common nuisance is that the higher-version Windows Media Player simply can’t play AVI videos which are edited with earlier codes, and vise versa. The AVI format is supported by all computers running Windows, and by all the most popular web browsers. It is a very common format on the Internet, but not always possible to play on non-Windows computers. Videos stored in the AVI format have the extension .avi. nAVI(new AVI),a new kind of video format. Don’t mistake it for the brother of AVI, and in fact the two has little relationship. nAVI is a variation of compression arithmetic ASF, but still a bit distinct from it. By increasing frame rate, nAVI enhances definition of ASF videos, but at the cost of the streaming attribute of ASF video files. The Windows Media format is developed by Microsoft. Windows Media is a common format on the Internet, but Windows Media movies cannot be played on non-Windows computer without an extra (free) component installed. Some later Windows Media movies cannot play at all on non-Windows computers because no player is available. Videos stored in the Windows Media format have the extension .wmv
The MPEG (Moving Pictures Expert Group) format is the most popular format on the Internet. It is cross-platform, and supported by all the most popular web browsers. Videos stored in the MPEG format have the extension .mpg or .mpeg The RealVideo format was developed for the Internet by Real Media. The format allows streaming of video (on-line video, Internet TV) with low bandwidths. Because of the low bandwidth priority, quality is often reduced. Videos stored in the RealVideo format have the extension .rm or .ram.
MOV:The QuickTime format is developed by Apple. QuickTime is a common format on the Internet, but QuickTime movies cannot be played on a Windows computer without an extra (free) component installed. Videos stored in the QuickTime format have the extension .mov.

Here I'd like to introduce how to Put Video on PSP, The simplest Way to Download Video to PSP
How to put video on psp? The Simplest Way to Download Video to PSP?
According to the Wikipedia figures, more than 25 million units of PSP have been shipped worldwide already. Lots of PSP users who are hungry for more content to put onto their PSP have to admit that downloading movies onto PSP via the internet is the easiest and fastest way.
The only problem is PSP can only support MP4 video formats (H.264/MPEG-4 AVC) while most movies and videos on the internet are the format of WMV, AVI or DivX. Chances are you have at least a small collection of videos on your computer hard drive – and those videos probably won't be supported because PSP essentially does not have "WMV playing" or "AVI playing" features!
Therefore, you will need a PSP video converter to convert the videos to be compatible with the PSP.
I’m using the ImTOO PSP Video Converter . And other PSP conversion software such as Aimersoft PSP Video Converter should do the job as well.
Due to its wide LCD screen, playing video on the PSP is a little different, and, to get the best quality, you are supposed to follow certain settings.
For video settings, you will need to make video resolution at either 368x208 or 480x272. The video bit rate should be at 400, 512 or 768 kilo bits per second (Kbps). The frame rate should be at least 29.97 frames per second so there is no shuttering when playing video.
For the audio specification, it is almost a criterion selection. The sample rate should be at 24 KHz and the audio bit rate at 64, 96, 128 or 160 kbps.
And also, ImTOO PSP Video Converter offers a free tool for your movies to PSP transfer - PSP Video Manager, which can be handled so simply to put video on PSP. Of course you can download this free tools to manage your PSP Video.
I would highly recommend downloading a PSP video conversion tool rather than use a generic video converter to do the video to PSP conversion as it is easier and you do not need to remember these technical parameters.

A team of computer security consultants say they have found a flaw in Apple’s wildly popular iPhone that allows them to take control of the device. The researchers, working for Independent Security Evaluators, a company that tests its clients’ computer security by hacking it, said that they could take control of iPhones through a WiFi connection or by tricking users into going to a Web site that contains malicious code. The hack, the first reported, allowed them to tap the wealth of personal information the phones contain. Although Apple built considerable security measures into its device, said Charles A. Miller, the principal security analyst for the firm, “Once you did manage to find a hole, you were in complete control.” The firm, based in Baltimore, alerted Apple about the vulnerability this week and recommended a software patch that could solve the problem. A spokeswoman for Apple, Lynn Fox, said, “Apple takes security very seriously and has a great track record of addressing potential vulnerabilities before they can affect users.” “We’re looking into the report submitted by I.S.E. and always welcome feedback on how to improve our security,” she said. There is no evidence that this flaw had been exploited or that users had been affected. Dr. Miller, a former employee of the National Security Agency who has a doctorate in computer science, demonstrated the hack to a reporter by using his iPhone’s Web browser to visit a Web site of his own design. Once he was there, the site injected a bit of code into the iPhone that then took over the phone. The phone promptly followed instructions to transmit a set of files to the attacking computer that included recent text messages — including one that had been sent to the reporter’s cellphone moments before — as well as telephone contacts and e-mail addresses. “We can get any file we want,” he said. Potentially, he added, the attack could be used to program the phone to make calls, running up large bills or even turning it into a portable bugging device. Steven M. Bellovin, a professor of computer science at Columbia University, said, “This looks like a very genuine hack.” Mr. Bellovin, who was for many years a computer security expert at AT&T;Labs Research, said the vulnerability of the iPhone was an inevitable result of the long-anticipated convergence of computing and telephony. “We’ve been hearing for a few years now that viruses and worms were going to be a problem on cellphones as they became a little more powerful, and we’re there,” he said. The iPhone is a full-fledged computer, he noted, “and sure enough, it’s got computer-grade problems.” He said he suspected that phones based on the Windows mobile operating system would be similarly “attackable,” though he had not yet heard of any attacks. “It’s not the end of the world; it’s not the end of the iPhone,” he said, any more than the regular revelations of vulnerabilities in computer browser software have killed off computing. “It is a sign that you cannot let down your guard. It is a sign that we need to build software and systems better.” Regardless the security doubt, people with iphone enjoy themselves much. Especially with multiple iphone conversion software such as Xilisoft iPhone Video Converter, which can convert all video files such as MOV, MP4, RM, RMVB, DivX, ASF, VOB, 3GP, WMV, MPEG, AVI to iPhone movies., large quantity of source can be available. A perfect iphone converter can be available, therefore iphone are still popular among different people. details on the vulnerability, but not a step-by-step guide to hacking the phone, can be found at www.exploitingiphone.com, which the researchers said would be unveiled today. Hackers around the world have been trying to unveil the secrets of the iPhone since its release last month; most have focused their efforts on unlocking the phone from its sole wireless provider, AT&T;, and getting unauthorized programs to run on it. The iPhone is a closed system that cannot accept outside programs and can be used only with the AT&T;wireless network. Some of those hackers have posted bulletins of their progress on the Web. A posting went up on Friday that a hacker going by the name of “Nightwatch” had created and started an independent program on the phone.
download the software and install it again, or check you operation system may be somthing wrong, or go for the web search for operation step.Good luck!

what is DV? Introductions come following: DV stands for Digital Video - video captured to a PC from a digital camcorder. There are two methods of storing DV video data, that is, type-1 and type-2. Both are stored usually in AVI files. Any DV stored as type-1 cannot be used with VfW-based editors. Microsoft provides DV encoder and decoder filters for DirectShow only, and will not provide support for encoding or decoding DV video data for VfW. DV Type-1 Method The native DV interleaved stream that is produced and consumed in I/O with a DV device contains DV compressed video and pulse code modulated (PCM) audio data. This single interleaved stream can be stored in an AVI file as "ivas" stream (for interleaved video/audio stream). Microsoft refers to this format as a type-1 DV AVI file. Because the type-1 format stores data as a single AVI stream, type-1 DV AVI files are not compatible with VfW. DirectShow, however, easily handles type-1 data streams by routing the streams to a DV Splitter filter that produces a DV-encoded video stream and one or more PCM audio streams for playback or subsequent processing. DV Type-2 Method Interleaved DV data can also be split into a single video stream and one to four audio streams within an AVI file. Microsoft refers to this format of storing DV data as type-2. This format has the advantage of being backward compatible with VfW, because it contains a standard video stream and at least one standard audio stream. The type-2 file format requires a small amount of additional processing to split and multiplex the DV stream during the functions of capture and transmit to IEEE 1394 DV devices. Recently HD DVD has been focus of all the manufactures and subscribers, and DVD related software industry develops rapidly, here I’d like to recommend a newly released software named Xilisoft Video Cutter, which is powerful video cutter free trial software which could perfectly assist you to select and cut your favorite segments in one file, and cut out the segments you dislike.
