Here is something about AVI,Video for windows

AVI is considered by many to be an outdated container format.

There is significant overhead when used with popular MPEG-4 codecs (XviD and DivX, for example), increasing file size more than necessary.

The container has no native support for those codecs' modern features like B-Frames. To circumvent this problem, cumbersome hacks (programming) are used, causing incompatibilities in some players. Hacks are also used to implement subtitles.

The highly efficient H.264 codecs use even more compression tricks, and thus are even more ill-suited to the format, particularly Main and High Profile.

Despite its limitations and the availability of more modern container formats (see Matroska, Ogg and MP4), AVI remains popular among file-sharing communities.

This is probably due to its high compatibility with existing video editing and playback software like Virtual Dub and Windows Media Player. Even many video converters support converting .avi ,too.

 :DWhen u googled video converters on the web, u will find top ranking softwares ,such as Xilisoft video converter ,supports almost all the popular video formats on the market including .avi. u can even get one trial edition to have a test

The tendency has been to install codec packs like ffdshow to augment DirectShow, using AVI as a common-ground, lowest-common-denominator format.

 :DIronically, while the codec/container incompatibilities mentioned in the above paragraph have undermined AVI's near-ubiquity, the obscurity and tech-savviness of those involved in the file-sharing groups has rendered this irrelevant.

Projects based on the FFmpeg project, including MPlayer, xine, and VLC Media Player, have rendered most problems with viewing AVI format video files irrelevant, regardless of internal format or codec needed, due to FFmpeg's high compatibility.

In June 2005, DivX, Inc. released its own container format called DivX Media Format (.divx extension) to succeed the AVI + DivX combo. However, this format is basically an enhanced AVI format (based on the same RIFF structure) and so far, Cheesy has gained no perceivable traction in file-sharing communities where the DivX codec is popular.

how much space is wasted exactly? if it's a few kb then nothing to cry about.  x86 is stickin' around too. so is English. Tongue It seems to me most devices support mpeg just as much as avi files.

Hands On Preview SONY NW-A800



SONY, who release the new NW-A800 Walkman and now there is a hands on preview floating around on YouTube.

“This Walkman can play high quality videos, MP3’s or flick through your photo album, plays contents downloaded from Internet, podcasts or simply from your camcorder to watch your home videos on the run.

Packed with features, a high quality 2″ LCD with user friendly interface so calling up your files is easy and multi-format support so even your AVC, MP4 or most other file types are just a drag-and-drop away.

Yes, I have the same idea with you ,although it is old dated but it can also provide high quanlity of video for example the recent film PRISON BREAK is still use  this format and I think it is very widely used .Of course there are still other formats. While if you don't like you can use xilisoft video and audio converter to transfer one format to another !
