None of the three new ones worked. The only one that did was the .mpg file. It's even more odd because I installed a divx 3.11a codec, and I reinstalled version 4.12. I'm using the newest version of media player that there is, and I have directx 8.1 I think. Oh well, I guess I'll just stick to the large mpg files. It must be because you guys are encoding with a 3.x version of divx. I really don't like divx, not for its quality, but because the company that made it doesn't seem to serious about support for their product. Do you know where I would be able to get the codec for the mp4 file type? Thanks for all the help.
