I have been using an HR10-250 for around two months. I use the HDMI interface to directly feed my Panasonic plasma screen. Until yesterday, the interface had been a little flaky on startup, and I needed to toggle the resolution from 480p to 1080i a couple of time in order to get the picture to display properly. Yesterday, the picture started to deteriorate, showing large blocks of off-color pixels, which moved in bands across the screen. I powered down and restarted the unit and the HDMI interface was completely dead - nothing at all. I powered down the unit a second time, disconnected the HDMI cable and connected the component video connection: nothing. I then power-recycled a third time with only the S-Video output connected, got the welcome screen, then nothing. I called DirecTv and after an hour and a half of frustration with a less-then-stellar customer service rep (no, I cannot move through the menus because there is not video output!, yes the phone line is connected, yes I have re-cycled the power etc.) who kept insisting that this is the first HDMI failure she had encountered, I finally got to talk to a level three rep. The level three rep was cognizant of the HDMI failure problem and seemed to think this was happening with 12-15% of the "early" units, but also thought the problem had been resolved by the replacement of some coils on the HDMI card. - this would seem to pass the common sense test; perhaps the coils are part of a timing circuit, which would affect the resonate frequency of the HDMI interface and thus its stability? The level three rep did not seem unduly surprised that the HDMI failure also caused an S-Video out failure. So, DirecTv has dispatched a new unit, which I should have by Wednesday at the latest.
