Do to your system speed it will take a bit to render. No matter what codec you uses. Anyway, here is what I do. I render a vidio uncompressed. im an mpg fan so I bought a version of honestech mpeg encoder. It has many compresion options on both mpeg1 and 2 formats, Witch will give you the capeability to record to VHS useing NTCS compresion. that is what most U.S. TV's use. they have a demo version you can try. Its a cheep program for what it does. I think it would work for you in every aspect you seek. all but the speed of rendering. 640x480 is great for vidio to tv. remember just because it looks like crap on your system doesn't mean it will on tv. TV is low resilution and it make vidios look great. hope you have fun :)
