The only system I've seen persistently give trouble with DivX is WinME. If you're using Win95/98, the install/"Run me First" (to register the DLLs)/reboot works every time. I can't speak for Win2000... but I suspect that'd be no trouble, since DivX was fine with NT. DivX was designed for Win95/NT, and so alternative OS (like the media-integrated WinME) will give trouble.
Also, there are so many DivX renditions available at the moment, I'm
not sure what effect installing other renditions would have. Here's a link that'll let you find a few different ones: my suggestion is to take the tried and true DivX;-)3.11 Alpha build. The 3.2.2 seems to be pretty good (according to MBs), I haven't messed with it much as of yet.
Basic DivX;-), try 3.11 Alpha FIRST, and follow the instructions on the page:
www.divx-digest.com/software/divxcodec.html DivX Alternatives, and I've NO idea if these'll handle encoded stuff in 3.11:
3ivX,
www.divx-digest.com/software/3ivxcodec.html Angelpotion's MPEG-4,
www.divx-digest.com/software/apcodec.html Co-incidentally, 3ivX is supposedly offering QT4 for Windows compatibility... I may well switch to that sucker in the near future, depending on how tests go.
Anyhow, RTDPages and hoping the best to you in installing.
