Had my 921 installed yesterday. It would not update while the installer was here, but did finally take the L211 update later on in the afternoon. At that point I scanned for my OTA channels. The only station it would lock on was NBC out of Tampa, where with my 6000 receiver, I could get all the major channels (ABC, NCB, CBS, Fox, and PBS). Tech support just called me back and stated that this was a software issue they were aware of and nothing could be done until next software version came out. Is anyone else having this problem? Cannot figure out why I can only get the one channel when three of the other stations transmitters are in the same general area. I did check with people from a Tampa Bay HD site and they did state the channels were all working properly.
