It happens with all VDPAU deinterlacer and yadif=1 in mplayer. video_out CPU usage is around 70%. FYR, http://bugzilla.mplayerhq.hu/show_bug.cgi?id=2158 Tested with a NTSC DVD with a HDTV of optimal at 1360x768@60 I believe it's actually a telecined source. I don't have many interlaced source on hand but I remembered once play a general interlaced source it's the same case.
