I recently bought a used Series2 standalone from a friend, and I've noticed that the audio is slightly ahead of the video by a fraction of a second. It's often not noticeable, but is very obvious when something quick happens like a hand clap and I hear the clap before the hands hit. This is true for both live and recorded programs. Is anyone else experiencing this problem? I've had a Series 1 TiVo (standalone) for several years and have never had a problem with the audio and video being out of sync. The software version on the Series2 is 7.1a-02-2-240. The model is TCD24004A. It was upgraded from 40 to 131 hours by Weaknees.
