I experience something similar on my T430s. Video lags sound, and drops
frames. Uses almost 100% of one core. A workaround is to switch the
video to full screen, then it has no problems. Debian testing, latest
FF, latest flash plugin.

I didn't bother looking for a solution since I don't watch a lot of
videos, but I can reproduce the problem.
