After reading through the forums, I've decided to get the HR20. I'll keep Tivo in my bedroom, but it doesn't make sense for me to have a brand new HD TV and not have a decent amount of HD programming to watch on it.
I don't know any of you, but your posts and knowledge have helped me out. I do not fear the HR20, even though I REALLY like my Tivo. It's time for me to move on.
I got the HR20 for nothing from DirecTV. That's all I wanted out of them as a 12 year customer. I just called and told them I'd been with them, was happy with them, but not about paying $299.00 just to enjoy my new TV with them.
Based upon your tone, I don't think you'll miss the TiVo user interface at all. I was as hesitant as you are, but it couldn't have been any easier.
And regardless of what anybody says, having a little pop up menu on the bottom left of the screen that allows you to select a show to play, search, etc. while Live TV (or recorded) plays in the main screen couldn't be any cooler. And it's instantaneous.
Also, pushing the Record button in the guide once to record, twice to set a series link is just as cool too.
You'll be fine.
