I took a quick look at your other thread.
So this glitchy playback occurs on pressed dvds as well?..
and this playback issue is “fixed” subsequent to uninstalling your ODD?..
and consistently recurs when you run Fab again?..
Whoa, this is bizarre!
I’d look first to deleting upper and lower filters…you have some sort of I/O conflict.
You can run Img or VSO inspector and take a look what’s installed for filters.
Here’s an MS link for troubleshooting and editing the registry for the upper and lower filters (both Vista and XP):
I like t0nee1’s suggestion about VLC.
It’s the best little player out there…JMO…and it does not rely on outside codecs…it’ll play just about anything without issues. Plus, it’s free.
Still, you have a conflict.
