RE: [OT] Vista MCE DVD playback

[Paul Gale <groups2@xxxxxxxxxxxxxxxx>]

Mmm - did you try setting vsync on it yet? The version of nvidia
drivers I have here allow application specific settings of vsync - might be
worth exploring.

Also- have you tried only running one screen to see if the problem happens
- screen tearing can be related to graphics card performance, so cloning
may affect what you're seeing - worth a go maybe?

Paul.
