There aren't any options at this point, but I'm wondering -- is this full-screen? If we made full-screen Xv operations block until vblank (which would lock up the X server), would that be an acceptable option? It's actually very easy to do, just stick a 'wait for vblank' command into the ring right before the 'copy the new picture' command in the Xv extension code. It's just annoying when you're watching a tiny movie and your whole session stops responding. -- [EMAIL PROTECTED]
