In N. Texas, and got 1.9 last night. Two DVR's 7232, and one is the MRDVR.
The MRDVR took the update and looks great. Love the new look. The other now has no menu, no guide, no DVR access and even the channel info does show on channel changes. Also the face is blank when turned off. No clock. It will show channels and change channels with channel up and down.
I have unplugged it and waited 30 secs, and plugged back in. No change. Even sent a reset signal, no change.
