Same here ... and I use headphones.Yeah I am having somewhat the same issue but in my case Bob's voice is very low and especially at the beginning. The intro music is quite loud.
One thing mentioned by Scott was offering customers the option to pay for TiVo software on Dish DVRs. Seems to me that this might only appeal to former TiVo users... I think the vast majority of Dish DVR users are pretty happy with the software. It's not perfect and people want add'l features, but these features aren't generally anything that TiVo has that Dish doesn't have.
