Thanks everyone for their responses, looks like the P4 will become the new
front end with a shiny new 9500GT on board and I will be trying VDPAU, the
Athlon 2800+ will be the replacement backend and the P3 1Ghz will be
relegated to the bedroom as an SD frontend only....
So many new things to learn now I have a TV capable of showing things like
they should..... And I thought I was all done with Myth box building :)
