Thanks for all the help guys.

I found another program on the Web called DVD to AVI at http://www.dvds-ripper.com/

It works really well all my audio comes with it, the only problem I have is if I say in output "No compression leave as original" it turned a 1gb file into a 28gb file, I then stopped it, and applied an MPEG-4 codec.

What is the difference between Mpeg-4 V1, V2, V3?

Thanks

James

Microsoft thought that its Advanced Streaming Format (ASF) was going to be the fileformat for MPEG-4, so the company built its implementation of the draft spec codecin an ASF file inside Windows Media Player. Had ASF been the file format for MPEG-4,this would have been an interesting beta prerelease. However, the standard actuallyadopted QuickTime as its file format, so MS ASF files aren’t MPEG-4 files. After MSMPEG-4 v3, the next version of the codec was renamed Windows Media Video v7 toavoid confusion with the real MPEG-4, and to bring the numbering into sync with therest of the Windows Media architecture.

From http://www.benwaggoner.com/articles/...Mpeg4v3f.3.pdf

So MPEG-4 v1/2/3 were precursers to WMV and DivX/Xvid, and therefore not the best MPEG-4 codec to use. (These are essentially proprietary versions of the MPEG4 codec.)
