How do you like the Tivo compared to this? We went from TiVo to a Dish ViP722 and have been happy enough. I feel like Dish is one of the few services that actually makes a somewhat decent guide / menu system for their DVRs. That said, there's some interface elements from TiVo that we miss, but it's not a deal breaker.
I had no complaints about the Dish DVR - it did everything I wanted it to - but without the service it's obvioiusly quite useless and I had to send it back, anyway. I know many people have problems with the Tivo Premiere, but I'm a fan. I really like how, when fast-forwarding, Tivo playback backs up a bit to allow you to catch the beginning of when the show resumes.
I think they're both very good products, both useful with their respective services.
