Thank you SO much for the explanation.
All this time I kept thinking, "How can these idiots keep
referring to the ATI Remote Wonder as an IR device?",
because I have one and it emits NO IR whatsoever.
Now I see that it should be possible for me to abandon
the kernel module, ati_remote, in favor of LIRC support.
I much prefer LIRC support, which I use in another MythTV
box, because I can execute whole commands and scripts
with it. With ati_remote kernel module, all I can do is send
keystrokes, which makes it very hard to execute scripts.
Your entertainment setup sounds extremely nice, quite
clearly the "cleanest of all possible home-theater setups".
Congratulations on building what sounds like an amazing
Thanks again for clearing up my confusion.
