I use Win98SE and began having problems after downloading a
particular video and/or installing ACE Mega Codecs. Have removed
as much as I could find, rolled back WMP9 at least a dozen times,
reinstalled OS at least 3 times, run all the freeware registry cleaners, antivir and spyware programs.
Any media player simply freezes when trying to play a video file, which
includes WMP9, Media-PlayerClassic/RealAlt., Quicktime and a few other
freeware players. Is probably a script or conflict from the Ace codecs.
Found zero help at the msn forums whose only advice is upgrade to XP.
A freeware video debugger would be helpful.
