This is a weird one and happens quite often - but cannot be repeated on demand. The Tivo is a P4. When using FF/RW and Jump Back buttons frequently, the audio will sometimes (as best as I can describe) go - "off track" during playback of recorded shows. Kind of like the sound a multi=track reel to reel tape recorder would get if the tape wasn't on the heads right or something. It is still in sync - that is not the issue. In my best estimation it's either - Gone from stereo to mono or Gotten out of phase. Some people might not even notice but I worked in recording studios and have engineered my own recordings as well - and it's very noticeable. This usually only seems to happen when I'm skipping around a lot. Skipping back/forward again usually will correct it either on the first try or after a couple attempts. Yea - WERID right? The TV is a VIZIO VX42L HDTV10A - and the P4 is plugged direct via HDMI - no switches or other stuff going on - but that shouldn't matter - it will only reproduce whatever audio it is being fed right?
