[mythtv-users] Australian newbie setup

[Marten]

I have been lurking around reading this list for some time now. The
Myth TV bug has bitten now and I would like to build a machine on a
budget.

I live in Melbourne and should receive the free to air DVB channels in
my area. My plan is to not upgrade my existing TV so I am not
interested in meeting HDTV specs. My aim is to use 2 of the DVB cards
to receive the SD digital channels and play them via RF TV out.

I do have an old box collecting dust that may cut it as a backend

Plan A
Use my old box, P3-600 with 600meg ram as a backend and build a front
end with an Xbox ?

Will an xbox handle SD live / recorded video ?
Will a P3-600 be able to keep up recording / serving SD content ?

Plan B
I purchase a new PC to setup a front and backend in one box. What spec
would be the minimum to handle Australian SD channels?

Currently I plan to install with Gentoo
