Normally, I don't post to forums, but I felt compelled to share my very different experience with the HR10-250 HD DVR. In all, I have owned seven sat-based DVR units over the last 5 years, and interestingly, of the four different models I have owned in that time period, three of them were the exact same models that the author owned (though my first model was actually the predecessor to the Ultimate TV; the E* Dishplayer 7200).
That's where the similarities between our user experiences end however. I have never experienced a serious software glitch on my HR10-250, and the user interface is basically the same as on all Tivos, which is stable, efficient and user friendly (the latter being of great value to those of us with non-technical family members - in my case, my wife, who would never support all the time and money I commit to my HDTV experience if it weren't for her miraculous adoption of the Tivo interface). The guide can be sluggish at times, and I do miss the PIP feature that my Ultimate/Displayer offered, but overall, I think this is the best setup out there - at least until the MPEG4 models deput.
Regarding the remote, IMO the classic Tivo peanut remote is ergonomically excellent - except for the 'skip back' button and 'power' button being too close in proximity and of the same size/shape. I think I prefer the first-gen Tivo remote. I could also do without the prominent 'thumbs-up/down' buttons consuming some valuable real estate. In fact, there aren't many other remote design that have lasted so long and been copied so often. Not to suggest it couldn't be further improved, but clearly, this design has been well accepted by the general public.
I do get the occasional audio blip mentioned by another poster, but I find that my OTA HD picture quality is actually similar to most of the sat-based HD content I watch. In addition, I have never experienced the HDMI handshake issues that many users have reported, so either a patch was pushed out to resolve this, or my TV just happens to agree with the HR10-250's HDMI protocol.
All in all, I am almost completely satisfied with my HDTV setup (for now), and that is a level of satisfaction that I have rarely achieved in my technical or automotive life!
