screen is shaking

[bobfishtf]

i calibrated the lag for the tv, and the notes hit just fine at the right times, but when there is a lot of notes on the screen it looks like the game is lagging....any similar trouble or possible fixes?

Actually, I also sometimes get a "screen shaking" thing going on. It only seems to happen when there are four players, and a bunch of notes (possibly just when overdrive is on?) on the screen at once. The screen shakes and glitches like there is a little gnome inside the TV jumping up and down. Doesn't make the game unplayable, but it IS annoying as hell.

Is there another thread about this? I'd be curious to hear if there was a solution.
