Hi, I have a problem with the divX codec.. Whenever I try to play my home made DivX files (no not movies

) the picture freezes but the audio continues to play.
I know its not a problem with the files themselves because they used to play fine before, and I know other people can play them.
I think it has something to do with Doctor ****tard aka Doctor DivX which I downloaded off
http://www.divx.com, when I had it installed it would ask me to purchase the damn thing before encoding anything.
After I managed to delete it and installing NiroCodecPack I could encode fine, but now playback wont work.
Any ideas?
I think I used DivX 5.02 when encoding them.. DivX 4.12 seems to work fine.
PS: DivX movies work fine, so its a weird problem.
