Yeah, I'm not throwing away my S2 DirecTivos, but I'm not going to be purchasing an HR10-250. I will definitely give my opinion on the new non-Tivo DVR. I plan on picking one up after I get back from the meet in 2 weeks.

To be clear, the new HR20-700 doesn't support dual live buffers, but does have dual tuners and can record two things at once. It's just that you can't switch between the two tuners while watching live TV. The 2nd tuner just sits in the background doing nothing until you want to record something while watching something else (or recording two things).

HMO isn't available yet, but I would be surprised if something like that didn't come out eventually. The box has ethernet and SATA ports on the back. I doubt they would be there if there wasn't an intent to use them at some point. I guess you could argue that the USB ports on DirecTivos are still supposed to do nothing...
