ok I'm having a major problem with re-encoded divx files. Im taking a mpg, and trying to convert it using exact steps as posted on this board, and I only get a black screen and in the propertie sof the file it says the video is 0 kbps. Now i've done a ton of re-encoding mpeg2 and dvds and have delt with a lot of mpg encoding, but I've never run into something like this, especially not with divx. If anybody can help, that would be great thanks.
