I've seen such artifacts myself too. Builds from less than one week
ago are fine. I suspect the problem comes from one of the optimization
patch that were committed to lavc.
I think you'd be better of reporting this problem to ffmpeg mailing
list, as that's the library that MPlayer uses to decode H.264 files.
I am disillusioned enough to know that no man's opinion on any subject
is worth a damn unless backed up with enough genuine information to
make him really know what he's talking about.
