The framedrop functionality can be improved, and I've tested enhanced versions of it. However consistent "drop every second frame" is not doable for all sources because of the way frames depend on each other; you can't skip decoding of odd frames and only them if motion compensation in even frames refers to the odd ones. > I am using vdpau but my card maxes out at decoding 48 1080p > frames a second.

If you're using an svn version of MPlayer, then the better VDPAU support in git can give improved performance. However the difference is unlikely to be big enough to improve from 48 to 60. But there is another alternative, using (possibly threaded) software decoding. Is there a reason why you'd need to specifically use the hardware decoding in VDPAU? > Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz I think this should be plenty fast enough to do software decoding of 60 Hz 1920x1080 video with 4 threads. If you haven't looked into threaded decoding before, git clone git://repo.or.cz/mplayer-build.git and see the README for some thread-related information. Depending on your Linux distribution there may also be suitable binary packages.
