I really like new technology, especailly as it goes to watching TV , and DVDs. I remebr time-shifting with VHSs and looking at laser disks. Anyway, I have had cable, stalllite and reviewed fiber optics.
Right now I have DishNetwork with 4 TVs hooked up ( two HD and two standard). I have two DVR recorders, 622 and 722.
My best HT system is in the den and I have the 722 connected via HDMI to Marantz 8002 then to 37" (largest that would fit in Amoire cabinet) Vizio LCD TV.
The PQ with the 722 seems to be better than the 622, but if so not by much; my current TV only supports 1080i.
Anyway, I can record HD. It also records HD anything I am watching and you can pause up to an hour.
The only downside is with either the 722 or 622 you can only have two TV streams. If the second TV is in use ( which in my case most of the time it isn't), then you have to watch what you are recording. This is about the only
advantage cable DVR ever had you could record and watch simutaneously.
However one great advantage of the DishNetwork DVR is that you can set a pre recording then turn the TV on in the middle of the recording and go back and start watching the recorded TV show at the beginning with all the pause fast forward, etc. controls, while the recording is still going on.
The capacity of the 722 is very good: 350 hours recording standard 55 hours recording HD.
It doesn't sound like the DirectTV or Tivo can do these same things the DishNetwork does.
Maybe you should consider changing to DishNetwork
I also looked at AT&T uVerse, At first it looks good from the specs, One DVR four recording streams, etc. But when you look further you find that you are bandwidth limited and also DVR palyback is limited. I know several people who had it and then went back to satellite.
