<div>I'm already at the fastest processor a Pundit will accept, so I'd have to scrap my whole nice form factor frontend to do that. I'm using OpenGL sync, and deinterlacing is already disabled. I haven't played with audio options at all, but I don't think that can be it, since if I turn off XvMC, NTSC plays back fine, but with it on, it plays back slow (not stuttering, just slow-mo).
</div><br>I'm out of town this weekend, but when I get back, I'm going to try compiling mplayer with xvmc support and see if that has problems playing back too. That will at least either eliminate myth from the equation or point to myth as the culprit.
