Hi,
When I change between the menus and watching tv I get a momentary loss of sync on my TV, about half a second or so. I guess my video card is changing its refresh rate or resolution or something. Has this happpened to anyone before? Is there a way to force an nvidia card to stick to the one rate?



PS I'm refering to vertical sync loss ie the picture tears up badly for about half a sec. Nothing to do with audio sync.

Have you got exclusive mode set in vmr9, MP config\directshow filters\video renderer settings, try changing.
