So I learned the hard way of another bug.
I had yesterday turned off PTAT on the LR HWS. Today I tested to see if it would play an EHD. It did, but God awfully slow to start up the movie. Too bad, so sad.
So I looked at the MBR HWS from the LR HWS. 75% full. I erased all the PTAT recordings. Tried to go back to LR HWS DVR. No dice. It stays on the MBR HWS PTAT screen.
So I turned off the LR HWS for a few seconds and turned it back on. No luck. Turned it "off" again.
I had to go to the MBR HWS and turn off PTAT there. Came downstairs and turned LR HWS back on and could go to DVR.
Glad I didn't have to do a RBR or cord pull. But the MBR HWS is hard to get to, being behind a plastic wall due to renovations.
I hope this gets fixed.
