As do I. That's 5-10 channels, not 100 HD and 500 total channels that
I can record on the DTV DVR.

So it's my understanding that if the channels are encrypted that the HD-PVR
really doesn't do what you suggest above. I must be misinformed. Are you
saying that the HD-PVR removes all forms of copy protection from encrypted
programs? Or are you suggestion that an STB cannot place any
encryption/copy protection on a composite output and that's why it works?

Anyway, the HD-PVR isn't a solution for me. It's too expensive and I'm not
going to spend my money that way and be left to deal with all the problems
of running all that hardware. I'm sure it's a great product, as is the HDHR,
it's just not for me at this time. But I am certainly NOT trying to impugn the
device. However at $204/channel at NewEgg it's certainly not cheap.

My thought here, only for the sake of discussion, is to simply
consider how do use
Myth in a somewhat less stand-alone, more integrated way with other devices.
It's possibly just me but I see some value in a very small box, like the Roku
player, that runs Myth and controls many DVR devices around the house. It
doesn't solve all the problems, but it would give me one place I could program
them and could be done by a very low-power inexpensive machine running Linux.

Just a thought.
