Which one is better than the other? My source is the Babylon 5 DVD, which is a 16:9 NTSC 29.97 fps interlaced according to dvd2avi (the episodes were shot in widescreen so are shown letterboxed). When I load a simple avs into VirtualDub and advance frame by frame, I notice that all the CGI shots have a different frame for every frame advanced, but any normal film part has a duplicated 5th frame. After a lot of research on this forum, I found that these 2 filters did the trick to smooth out my resulting KVCDx3 encodes. In dvd2avi I do not select force film, and I make sure in tmpgenc I'm encoding at 29.97 fps.

Only problem is with Bob, the resulting image has the wrong aspect ratio. It always looks like there's ~1.5x zoom on the image, meaning instead of a letterboxed image I get almost a pan and scan one. Things look fine with FieldDeinterlace though... so maybe I should stick with "if it ain't broke don't fix it" but I just wanted to hear what you guys think! Thanks.
