hi guys i'm sure you are all tired of hearing this crap and i did have this working once before, i duno what happened but no matter what codec pack i install or uninstall or what doom9 dvdr guide i read nothing works i cannot play movies in real player becuase says im missing a codec windows media play says connecting then error downloading codec but it plays the picture without sound you name it i had it installed also i cannot get rid of that damn error message on winavi that says u need real codec 0.0 or whatever i mean this is very frusterating can someone give me some kinda clue whats going on?
.xvid is an extension sometimes used for raw XviD streams (usually .m4v is used). I am not aware of any dshow parser for raw MPEG-4 part 2 streams. Sounds like you are talking about an avi though in which case it probably uses AC3 audio and you are missing an AC3 decoder. If so, then installing AC3Filter or ffdshow would fix it.
Im not sure what the problem would be but you might try installing the K-Lite Codec Pack 2.63 Full and then try using your media player. Its got everything and anything in it.
Could be that particular ffdshow build was compiled with MSVC7/8 and you are missing msvcr*.dll which would be a dependancy so the filter failed to register. Could be something else like it is a gcc build which would require SSE which your CPU might not support (old athlon, etc.). I really wouldn't recommend installing codec packs.
