There is no Winavi 9, someone has just changed the colour of Winavi 8 and redistributed it as Winavi 9. There is also reported to be a type of malware in this version which adds a new service to Win XP which hogs system resources and slows down your computer. Best to avoid this.
You will find that due to the excellent new compression algorithms used in version 8 that there is very little difference in quality between the various settings unles you are going to view them on a 40 inch plus tv. Also, remember that if you are converting from divx etc. to dvd there is no way that you can improve on the original compressed file so there is no advantage in having a large dvd file size. If you experiment with the various settings and compare them, you will see what I mean.
You will probably find that Winavi uses 100% of your processor's resources while converting, so it's wise to close other programs until it has finished, especially whilst burning, if you want the best results.
andymac Try a new completely free program called SUPER. You can download it here http://www.erightsoft.net/home.html It will probably solve all your problems as it will re code almost any format quickly and with excellent quality. Enjoy
Download Fairuse light from the link below. It's free and gives perfect results everytime and use the internal xvid codec rather than divx. You can't go wrong with this and I've been using it for years. Enjoy. Winavi is good for avi to dvd conversions but for dvd to avi use Fairuse.
At this time, there are numerous sound problems with Winavi 7.7 including sync problems when converting to anything other than dvd. Until the next version is released, unless you only convert avi to dvd, it is best to revert to 7.6.
No problem here with Winavi 7.7 or 7.6 with vobsub but make sure that the filename of the subs is exactly the same as the avi file name or it won't work. Some sub files have the words (subs) in the file name and this has to be deleted. Hope this helps.
I have been using WinAvi 7.6 for some time now and also have chapter points set at 5 mins and have no problems with freezing etc. either on standalone players or PS2. However, there have been some reported problems of this nature caused by the auto setting in WinAvi. Try using either the PAL setting or the NTSC setting (depending on your requirements) rather than auto setting and see if that makes any difference on the PS2.
I only use Nero to burn the files to dvd, but the audio folder should always be empty and you just need to open the video folder and burn it's contents to dvd.
As long as the subtitles for each file are in the same folder as the file and have exactly the same name, vobsub will automatically add the correct subtitle to each file.
