Stuck PTAT (update)
Had the same problem tonight. PTAT stuck ENABLED when I've never enabled it and the DVR setup menu says it was already disabled. Repeatedly selecting disable in the DVR setup for PTAT did nothing. According to the Joey tuner screen, not only PTAT was on, but one of the other Hopper tuners was stuck recording another channel, even though the Hopper was off and nothing was scheduled! Soft reset did nada. Called DISH. They said that THEY'D disable PTAT, but that was impossible now because PTAT was already recording! I'll see tomorrow evening I guess. Nice, a feature you can't disable once it's stuck! Brilliant!
On the bright side, I score a $5/mo reduction for 6 months. Guess they are aware of the problem.
UPDATE: PTAT was disabled remotely by DISH on tuner 3. Tuner 2 not stuck recording. I guess what they meant was that they can't remotely disable PTAT while a show is in progress.... Ah well.
