New to the forum - and just about a month of HR20 700 experience (not much without errors), but have encountered something similar to what you are describing - along with some other "bugs" (and we subscribe to HBO, and HD package, Sunday Ticket and Super Fan - Showtime and Starz have been added to our programming):
Problems with HR20 700 (HD DVR) - this is our 3rd receiver (receiver 1 had the same issuses, additional problem with receiver 2 described below):
Going to the HD Channel block and using channel (+) to go through channels:
70 – (HBOH) - Channel not purchased (721)
71 – (SHOH) – ok
72 – (ES2H) – Program not available in your area (727)
73 – (ESPH) - ok
74 – (UHD) - Program not available in your area (727)
75 – (TNTH) - ok
76 – (DSHD) - Program not available in your area (727)
78 – (HDNM) - ok
79 – (HDN) - Program not available in your area (727)
Note, I can go downstairs to the basement (HR15 HD receiver) – and all HD channels come in fine.
Continue to channel 80, which actually is not available (and displays the appropriate message) because we have local channels instead of regionals, then go back down the HD channels using the channel (-):
79 – (HDN) – ok
78 – (HDNM) - Program not available in your area (727)
76 – (DSHD) - ok
75 – (TNTH) - Program not available in your area (727)
74 – (UHD) - ok
73 – (ESPH) - Program not available in your area (727)
72 – (ES2H) – ok
71 – (SHOH) – Channel not purchased (721)
70 – (HBOH) - ok
So the error messages have flipped to the "opposite every other channel".
Also, receiving error message “Searching for Signal on Satellite on 2 (771)” when attempting to tune in the second local channel. For example, tuning in local HD channel 11 (WBAL), signal is ok, then, tuning to the next local HD channel (2, 13, or 45 – it doesn’t matter), getting the error message (771)… need to go to a standard digital channel (202 or any other, really SD channel) so the message clears from the screen, then directly tune into the “2nd” local HD channel (2, 13, or 45 - doesn't matter)… and the channel tunes in ok.
We had a technician come to the house and he forced some software updates, which corrected the above problems, but unfortunately, caused an error when we attempted to DVR a show and watch another. We would get an error message saying that we were unable to watch another program because both tuners were in use.
After calling tech support, and resetting the receiver we were able to record one show while watching another, but all of the HD problems returned again.
We're also getting some minor glitches like the time/status bar freezing (usually around 10-11 minutes) into a recorded program.
Our second receiver did not show both sets of local channels - the HD (WMAR, WBAL, WJZ, etc.) channels showed in the guide, but not the standard digital channels (BA2, BA11, BA13, etc.). The techs couldn't get this corrected, but we haven't experienced this problem on receivers 1 & 3.
As of right now, after many hours on the phone with Tech Support, HD Tech Support, troubleshooting, swapping receivers, 3 in-home visits from local DirecTV techs, etc… we are awaiting the 4th HR20 700 HD DVR receiver, and another visit from our local technicians.
ANY HELP WOULD BE GREATLY APPRECIATED…
