I've had that box unchecked since day one. Maybe it's a version issue I'm using My X50v all the time now.
Guess I should change my profile and the version of the media player in that is Version 10.0 Build 14280. I'm also wondering if it's a VGA issue. I don't use any enhancers like oz_vga or se_vga, I've tried the Tweaks2k2.net brute force hack, and picard_beta's Tweaked GAPI driver on and off but it still looks the same. Why do I get the feeling this is yet another hazard of being on the bleeding edge?
