Hi people!

I have problem with encoding DVDrip to XVID. I use SmartRipper for rip, DVD2AVI for conversion to *.d2v, avisynth with mpeg2dec for resizing and VirtualDub for encoding to XVID. Also I use Link2 frameserver utility for conversion *.avs to *.avi for CCE. When I run VirtualDub in Video I checked Fast Recompress (my *.avs source is YUY2 colorspace) and compression XVID. Encoding without problem. But if run Link2 and load my XVID *.avi file, link2 show that colorspace is RGB24.
Questions:
1. Advise me other programm for identify colorspace in *.avi files.
2. How make that colorspace XVID *.avi file was YUY2 (less conversion between colorspace, more compression )?

With kind regards Yury.
