How do you plan to distribute your centralized myth around the house?
I have my main myth backend in the basement recording SD and then
connected to an rf modulator to go through the coax already running
through the house. Then I have x10 powermids on each SD tv with a
streamzap remote.
This only works because these tvs are never used at the same time,
although it wouldn't be too difficult to add a video card, sound card, IR
receiver and rf modulator for each TV. I've to find another way to send IR
back to base though. It just might be difficult to find a motherboard with
enough pci slots.
I've also switched everyone over to linux desktops + nice lcd monitors +
streamzap remotes, so that every workstation is now a nice entertainment
center. For HD I have a dedicated frontend for my only HDTV.
I'd be interested in seeing your solution for multiple frontends on a
single machine.
