OK I need to reach out to the TIVO community. I have a Series 3 Tivo which I am so excited about - however I am encountering issues with the digital audio. When the unit is plugged in the analog channels are fine - when you get into the digital channels they are digitized (garbled). So here is the breakdown: My TV is working fine - had a cable box prior and had digital channels. TIVO is working fine (had it working on another of my TV's). I replaced cables with brand new - just to be sure. Plugged TIVO unit into wall to make sure Unit was grounded well. I brought a small TV to test all the connections with (so I didn't have to climb behind my big TV all the time) when I connected it to the small TV it had the same audio symptoms until I changed the Dolby Digital - PCM option to just "Dolby Digital" and it then worked on my small TV! So I unplugged the HDMI from the small TV (knowing it was working) and connected it to the large TV and still had the garbled audio. I have used all types of cables to connect and HDMI seems to be the best. TIVO wants me to replace it at a cost of $350 - tough to do when I have seen it work! I am thinking it is a cable card issue but would appreciate any experience and feedback someone can provide - this is so frustrating!
