I am having severe video playback problems regardless of the playback application including frequent skipping, audio/video getting out of sync and even an occasional crash ever since installing the elecard mpeg codec on my machine. The weird thing is that the playback problems are not isolated to MPG2 files but seem to be more widespread. I was wondering if anyone else has been experiencing this and what the best solution would be. Thanks Guys, Machine config is as follows:

Ga-7DXR motherboard (AMD 760 AGP)
512mb PC2100 Memory
sb audigy platinum
netgear fa310tx NIC
aTi Radeon DDR 64mb Vivo
windows 2000
latest version of all playback software and other codecs
