I have a new series 3 with two cable cards from Insight that I am having audio problems with. When I first boot my Tivo and it goes through the THX, my receiver plays audio in Dolby Digital mode. However once I go to live or recorded programming it switches back to PL II. I can't think that I have something hooked up incorrectly with it playing Dolby D on boot. So my question is, anyone else having a similar problem with Insight Cable?
