Well, the installer has come and gone and I now have the Genie DVR set up with a couple of clients. In regards to my aged Sharp LCD TV in the kitchen, we tried the component connections and it just didn't work out as the aspect ratio of the picture was squished. This TV/Monitor doesn't really support 720P or 1080i. It's a an older 1024x768 monitor. The installer used a second set of cables (rca and composite) from his truck to connect the Genie client to this TV. Not an entirely satisfactory situation, but at least it looks "okay."
With the HR44 Genie installed and and running I really like the speed of the unit and, obviously, the recording capacity. After about 5 or 6hours of operation there is no Pandora or YouTube showing in the Extras menu but I believe that takes a few days to populate. i am guessing the same is true for the Genie recommendations feature ("TV Shows"). It just says it is updating and to check back in an hour. Also, when I tried to select some on-demand programming I just got the DTV logo in the middle of the screen and no programming. Would like to hear if these are common complaints so soon after an installation. And, yes, the receiver says it is connected to the internet. I know this because I can get the Apps menu to come up.
