I have it too, same symptoms as everyone else.

I've noticed something though.. If I pause a second after I highlight the video I want to watch, I almost never get the lockup. If I scroll through and hit enter as soon as the video is highlighted, there's a high probability of the lockup.

People seem to be pointing at vdpau... Could it be something to do with vdpau + audio, too? I have everything going out of my nvidia card (honest to god nvidia card, not a revo or anything) via hdmi; it seems like it's within the realm of conceivability, at least, that there might be some interactions going on there.
