But you're talking about a system which includes a Front-End (and one which
supports high-def playback, at that).  That is not the situation I'm
dealing with.  The new system will be a Back-End ONLY.  My understanding is
that this reduces the host system CPU/memory requirements *drastically*, as
compared to a FE/BE system.

Why, pray tell, would I not want to run XvMC?  I'm using it now on the
existing (stand-alone) FE/BE system, and it seems to do just fine -- tho'
admittedly, I've yet to try playing back any high-def content.

I should hope so!

So then, Myth *does* use an IR blaster to control the HDHR?  If so, and
presuming multiple HDHR boxes stacked up on the shelf, I'd need multiple IR
blasters hung off the Myth box, *and* I'd need to jury-rig some way of
"dedicating" each IR emitter to *that* particular HDHR, with no possibility
of "crosstalk" between them.

This is starting to sound more and more Rube Goldberg -ish.
