Can't get XVID to work, Vdub+Moviemaker errors

[nhgawe]

I'm having problems with the XViD codec on my Vista 64bit machine. Windows Movie Maker will no longer play xvid avis correctly, it will only play the audio with a black screen. It also crashes constantly when importing new media or adding media to a timeline. Importing an avi into VirtualDub or Virtualdubmod says it can't find a decompressor for XViD. But when I go into the compression menu xvid mpeg4 is listed as a codec. And when I try to use Prism Video Converter to convert to AVI I get a statsfile not found error. All these programs recently worked fine. I think there's some codec confusion with my system, too many installed, or not the right one.
Currently in my programs list I have DivX Plus Directshow filters installed, the newest ones, recently installed the newest DivX suite, installed ffdshow latest revision cause it seemed that was what Vdub was asking for, except I never had this installed before to edit xvids with. I have Windows Media Encoder 9 series, xvid 1.2.2, and Celtic Druid's xvid 1.3.0 CVS which is supposed to be for 64 bit windows. I was still getting errors with it so that's why I went and got xvid 1.2.2. I'd rather not have the ffdshow pack at all, like I said I didn't have it before and things were working fine, was it the newest divx installation that messed everything up? I used to have klite codec pack and things worked then but I got rid of it. What to do?

I would uninstall them all and start again. In general, it's my understanding that the 32 bit version of the codec works with the 32-bit versions of the software, same is true for 64-bit SW - works with 64-bit codecs only.

Another thing about xvid, some times the files have the internal 4cc code set to "xvid" instead of "XVID". The lowercase 4cc is not recognized properly.

You can check the 4cc with this:
