Let the hive mind of Engadget get that for you.
"I need help! I want a small pocket camcorder but I'm not sure which one to get. I don't want to fall into the hype of the Flip because I worry two hours won't be enough. What should I be looking for when considering a small camcorder and where can I get a good quality one with expandable memory? Thanks!"
The HR20 suffers in comparison to the Tivo, but compared to the local cable company's Scientific Atlanta box, the HR20 is quite good. Even the so-called "HD lite" is better than my local cable outfit's, who is even more bandwith starved than Directv. If Directv can get their new satellites launched and solve their bandwith woes, most of their problems will be solved. I don't have a problem sticking with Directv.
Of course if I could get a fiber optic hook-up from Verizon in my part of town I might have a different opinion....
