Mine used to do the same thing... here's a sample video of my roomate doing doughnuts in the mall parking lot late at night while it was snowing.

The sound even ends up out of sync.

I have noticed video performance has become considerably better with changes in ROM (and the registry tweaks that come with it) but I haven't taken one to be 100% on this.
