I have always been a BIG Tivo guy, and made the switch (only because of HD) to the HR20 a week ago. From reading about all of the bugs I was kind of dreading it. But I have been very pleasantly surprised and don't really miss Tivo much at all. I love the dual tuners (I had a stand alone Series 2 Tivo hooked up to a DirecTV receiver, so I only had one tuner), and overall the performance of the unit is much better than Tivo. The HR20 is a little clunkier when it comes to responsiveness to rewind, FF, etc., and as good as the 30 second slip is, it still pales in comparison to Tivo's skip IMHO. I also miss Tivo's ability to play MP3's from my network, but I now use my XBOX 360 for that. I also have had to reset my HR20 3 times in a week, which is something that happened with Tivo maybe once every 3-4 months. But overall I don't miss Tivo much at all.
