Before investing in a solution like this, I was thinking of using the
Time Warner STB to handle it for me.  The STB has an AC outlet which
can be always-on or switched based on menu settings.  I was thinking I
could plug the HD-PVR into that receptacle and if I detect the HD-PVR
is borked, I make sure my firewire channel-change script adds the -P
CLI argument to power-cycle the STB on the next channel change.

I'm still trying to determine which errors in mythbackend.log actually
mean the HD-PVR is borked.  I get various errors from mythbackend on
HD-PVR recordings, but I've not power-cycled it for weeks and my
recordings are not zero-bytes.  Every once in a while I get a borked
commflag job, but that's it.
