Thanks Bill.

It's clear from these responses that I'm a bit remiss in terms of my
explanation here:

Sure I'd like to do this tomorrow using the software that available,
but it's not important to me. Really what I wanted to do was start a
conversation, understand what might be involved, and then maybe
propose the idea to the developers as an alternative usage. They could
then determine how to best do this within their vision of Myth.

My thoughts about the reasons for wanting this are:

1) There is a desire to watch HDTV
2) Much, if not most, HD content is now or soon will be encrypted.
Even SD material is already almost totally encrypted on Comcast which
is why I dropped them.
3) I've paid for this content and there's very little chance that Myth
is _ever_ going to really help me with this problem.
4) I'm not well versed in the HD-PVR area but I don't believe using an
HD-PVR solves any of the commercial flagging or streaming of encrypted
HD content to other machines.

Assuming others have a _roughly_ similar view of the problem set then
my thoughts are more like MythTV becomes sort of like a big TV cron
job server, keeping track of how I want to manage multiple DVRs,
potentially from multiple sources, and then just drives their hardware
for me. Once the programs are recorded on the DVR Myth goes back to
sleep. No hard drive issues, no recording direcory, no mythcommflag,
etc. It's a simple task and one that Myth is very capable of doing, at
least that's what I think.

True, I have to watch the programs using their hardware, but no one
has suggested any solution to that as far as I know, unless I'm
misunderstanding the HD-PVR as I think I still have to watch using the
same HD-PVR. I'm I'm a poor, out-of-work guy who's looking for a low
cost way to be more effective than the free DRV software in the
DirecTV box.
