Thanks to Roland Scheidegger I now get a perfect picture for all source resolutions testet so far. http://lists.x.org/archives/xorg-driver-ati/2008-July/006143.html http://www.vdr-portal.de/board/thread.php?postid=741778#post741778 There currently is only one known issue left: detection of inital field polarity. I don't think this is a big deal. After this I can start productive use of the patch on my living room VDR.
