So running multiple HD-PVRs (2,3 or even 4) is going to be easy for a
basic machine ?

OK.  Easy for me to set up like that.

I'll look into and test the DLNA exerience.   Thanks for the heads up.

I've been pricing hardware, so I realize that.  However, I'm frustrated
with the limitations of the satellite PVRs and my home won't work with
any system other than a Myth setup.  

Aside: my home is wired funny.   Most rooms have a single coax from the
utility room to the TV locations, supposedly for cable.   Almost all the
TV locations also have a Cat5 feed from the utility room.   

My satellite system requires 2 coax feeds from the LNB to the receiver
in order to view HD content.  I'd have to rewire the entire house to get
2 coax feeds to everyplace we want a TV.  

However, we don't have to do any rewiring if we can send content on the
network.  Thus I've got a choice of rewiring the house OR running Myth.
And I've looked at Myth in the past and been hankering to set it up.
Now I have a great excuse.

It did.  Thanks for starting the replies !
