Greetings!
I'm only slightly concerned about my new Premiere Elite unit. I just upgraded from my beloved Series 3 (which has been relegated to the bedroom TV). For the last week or so, I've had both Tivos up and running and things have mostly been great. I'm just working out some kinks with the Elite and getting comfortable with the Premiere UI.
But last night I was pretty annoyed. I watch a show on ESPN called Pardon the Interruption (or PTI), and when I fired up home theater and played the recording, I was very perturbed to find that there was no sound whatsoever! I fast forwarded through the whole thing and there wasn't any audio in the whole recording (which I set for 90 minutes to get Sportscenter too, which I fast forward through).
I tried everything I could think of, looking through audio settings in the Tivo and anywhere else I could find. I changed surround modes on my receiver. I even removed my Sony Google TV box from the chain to see if that was the problem. Nothing worked.
As a tech support professional, though, I know how to troubleshoot

So I went to the Series 3 in the bedroom, which is still recording all the same things it used to (since I pulled the Season Passes from it). I played the same episode and I DID have sound.
Next I tried transferring recordings from one box to the other. I put the Series 3 episode on the Elite and vice versa. Lo and behold, the Series 3 recording played with audio on the Elite, and the Elite recording had no sound on the Series 3.
So the problem is definitely with the Elite. What do I do? Should I be worried? How can I be certain that I won't get another dud of a recording on the Elite? I'd really rather not record all the same shows on both boxes.
Thanks for your help!
