What do you gain by routing audio and video from the sats through that
receiver to the myth-box, then back through the receiver to the TV?
IMO, anything an analog signal goes to should be avoided, especially
if you are going to digtalize it afterwards. Random noise just eats to
much bandwidth when being diditalized.

you got me confused there, too :-)

There isn't a cable that does that (at least, I haven't found one). I
am using Double or Trible shielded RCA - RCA cables from some
car-stereo shop (just to much noise behind my computers) and put an
RCA female to 1/4" male plug adaptor on it.

DVI is DIGITAL video interface. afaik component is analog, so even if
your dvi has analog signal, why not use vga?

> THANK YOU for any comments - I'm sure I'm missing something here.
