I found that the remote would work solid every time to switch from standby to on, but would not reliably turn the unit off. I could use the front panel switch to go back to standby and the remote would turn it on again from anywhere in the room. I took the batteries out of the remote last night, then this morning got the bright idea to shut the DVR down for a time by the rear panel switch so that some re-boot might occur. I haven't spent any time with it yet but it seems to be working. I'll keep you posted, if any buttons do not work I'll try the intensity test.
