"Unreliable" was perhaps a bit hopeful. That first success
watching the HD channels was the only one. Haven't since
managed a lock on any channel, even though I've powered off
and rebooted many times. I wonder whether I imagined the
initial success: perhaps I was actually tuned through my
Nova S2 HD card. Anyway now, I can tune the channels, but
I can't watch them.
