[mythtv-users] Myth w/Directv

[Adrian Townsend]

I have yet to actually get a mythTV setup running as
I'm also in the midst of moving so it's a bit of a
mess . .

The set-up I was envisioning was slightly different .
.

Backend with Avermedia M179
Large (likely 160 GB) drive with movies and such.

Frontend with cheap capture card just for watching TV,
The idea being that the backend would do any recording
and serve movies/videos but not hamper the network
with a simple live TV. No I won't have the pause
feature and such for live video but that's not a
useful feature for me.
This way I can easily add simple front-ends that can
all set a program to record on the backend and watch
movies off the backend but don't draw live TV off the
network
Is such a setup possible? Is there a particular reason
that it's a bad idea?
