I have two Blu-rays of 2010 and both have the same glitch. In the conversation between Floyd and HAL right before Dave Bowman appears, Floyd tells HAL "I can't take any of this seriously unless I know who I'm talking to." Right at the end of this when Floyd says 'Yes" his mouth doesn't move with the words. It's very quick but a glitch none the less. Does anyone else have this issue? My Blu-rays are from different sources. This wasn't present in the original DVD so it must have happened in the Blu-ray conversion. Aren't Blu-rays supposed to be perfect?
