TiVo R240140 140-Hour Digital Video Recorder
Rebuttal to "An electronics fan" commentary
Sounds like this person's experience is isolated.  We have our Tivo unit connected through a \\"complicated\\" A/V system where Tivo is NOT going directly from the unit into the TV.  There are no delays whatsoever. Everything remains completely in sync. Tivo is one of the best items I have ever purchased.
