I did not have heat issues... I removed the covers before I ever put them
into service based on all the things I had read.

That appears to be the same as mine

One thing that thread reminded me of is that module option:
"options lirc_zilog tx_only=1
This is something I set on my system (also preventative). Not sure if this
is something that only applies if you have the zilog kernel module loading
(I did use the blaster on these for a brief period, but it was too slow).

I record an average of 12 shows a day and frequently have all 4 of my
hdpvr's active for at least an hour during prime time... as far as I know,
I have never had one in the state you describe.

This is a definite possibility. The box may not like the rapid cycling?
I quickly determined that the "OK" button on my remote would wake up an stb
that was in standby (the standby screen actually says press OK to watch
tv), but it just brings up the OSD if the box is on. So I just added an
"OK" to my channel change script. It presses OK, waits 500ms, then enters
the channel number. I have never needed to check the status of my STB.
It may be worthwhile to determine if there is any button press you can send
that will wake the box if its off, but not do anything if the box is on.
Most of these boxes I have seen do not have a true "off" state.
