I'm trying to convert a 12gig+ .avi file I captured from my dig 8 camcorder into an mpeg2 file using tmpgenc. When I try to load the .avi file into tmpgenc, it says "file unsupported". I captured a small (20 sec) clip, and was able to use tmpgenc to encode that .avi file into an mpeg2 file just fine. The resolution of my dv .avi file is 720x480, and I'm running winxp. Let me know if you need any other specs about my system.
