I see - but I got this teartest video only in one resolution ;-) . However, VLC has some option to stretch the video, and I guess mplayer has that, too. Not that it's needed currently.

Yes, I used a debug output in that branch. When using mplayer, I get a *lot* of them - as is to be expected, about one per frame. For VLC, there's just 10 to 20 full-screen redraws during the entire (30sec) video.
With compositing disabled, VLC produces some tearing, but much less than with compositing (comparable to using the XVideo backend and compositing).
