I upgraded to DIVX 4.12 last week, and suddenly my VCD-compliant videos on my HD were desynching. I examined the 'properties' in Windows MP (v6 is the way to go!) and all of a sudden all the MPEG stuff was being handled by codecs from something called 'Lindos'. So I uninstalled DIVX and suddenly MPEG files will not play back at all! I get a black screen and the time bar does not progress, but no error either. I even reinstalled divx and still the same problem. Any ideas? I tried to update WMP but Microsoft doesn't seem to have any updates yet for the XP version, grr...
