--- Comment #7 from Jer Noble <jer.noble at apple.com> ---
To expand on this last comment, the decoder will pre-decode more than just the first frame in the queue. By seeking to every subsequent frame, you're effectively making the decoder work 2x to 10x more by making it flush all it's previously decoded but not yet displayed frames.

So yeah, if you seek at 60fps, you'll only keep up if you have a super powerful machine, because you're effectively playing the equivalent of ~6 videos simultaneously.
