I know nada about the SA boxes, but really, it ought to be possible
for us to have a single firewire channel-change program that covers
all set top boxes. They're all using libavc1394 for communications
(A/V Commands over 1394), which is pretty well defined for all the
basics we need. MythTV changes channels on most (all?) firewire set
top boxes internally for firewire recording devices, anyway... (not
that I have time or desire to do anything about this myself right now,
I'm just sayin').
