I've only got one input (PVR-150) at this point.. I have a feeling that eventually the evil cable companies will force me to have a cable box (none yet), which will mean some re-thinking my setup... IR blaster... or what have you. I'll simply have to upgrade at that point ;-)
Check out http://www.mythtv.org/wiki/index.php/ComponentOut for come
good Component Out tips.
If your TV works properly with DVI, try that. Although, most TV's treat
DVI as a "pc connection" which, for some vendors or TV types, doesn't
work out as well. Also, be aware that some TV's don't do DVI correctly
(a co-worker's 1yr old projection has a DVI port, but isn't supported to
be hooked up to a PC).
Component out is as good as HDMI, except for the fact that there is
digital->analog conversion in there (and theoretically there could be
some loss involved) while HDMI is all digital to the TV (less subject to
interference along the wire). However, Component Out doesn't have the
possibility of any DRM (which HDMI might).
