I'm using the full version on WinAVI. I followed guide at http://www.dvd-guides.com/guides.php?category=othertodvd&name=winavitodvd to convert but after it converts the video is choppy. Here is what WinAVI has to say about the file.

Video Renderer
Default DirectSound Device
MPEG Layer-3 Decoder
XviD MPEG-4 Video Decoder
AVI Splitter

Now the guide says something about having the right codec and I have a Xvid codec installed for encoding and decoding so I don't think that could be it. I've tried a few different setting in WinAVI as well so any help would be appreciated. Thanks. By the way, the video isn't copy to begin with either. Also my recorder is a NEC 3500a and i'm trying to write to Memorex DVD-RW media at 2x. Thanks
