Glad someone else asked this since I've been stewing on it for months. I
think Brian has it figured out. If the STB, in my case DTV, is plugged into
the TV or receiver using HDMI then my theory is the device somehow notifies
the STB when turning off and the STB glitches while evaluating DRM or
something....  The HDPVR recovers but leaves the recording with what I
would call a "period of ugliness" that commskip cannot get past and usually
dies. Plus when I hit this region during playback sound gets out of sync
and I have to exit return to correct.

I keep planning to unplug the hdmi but my wife does like to watch DTV
directly, especially with Myth liveTV being a work in progress (sort of).

Questions (assuming you can get past the use requirement that someone would
like to use their STB for two purposes and not pay 10+ month to get around
this one issue):

Maybe I should just split the rgb / spdif output somehow instead and not
use hdmi?
Or is there a cable that would block, or not support at all, this "reverse"
signal?
Is this what "reverse sensing" is all about?
Maybe a HDFury would mask it? Been thinking about getting one of those for
when D-Day comes anyhow.

Thanks,
Eric
