You recall correctly.

Yep, only works with the iMON remote (or a universal programmed to
emulate one), so far as I can tell. Just tried getting mine to power on
with an MCE remote, no dice. Powers on just fine with my usual remote

It picks up other IR signals, it just ignores them. The iMON devices do
signal decoding in hardware, and are only wired up to decode two
different (and very specific) protocol sets -- whatever the one the iMON
remotes use, and the RC-6 command set the Windows Media Center Edition
remotes use. And it can only do one or the other at a given time, it
can't do both.

Yeah, the PAD isn't the best remote around. I actually use a Logitech
Harmony 880 with my iMON receiver. Any universal that can programmed
either as an iMON remote or as an MCE remote should be viable.

Someone posted a patch in the mythtv wiki a while back that partially
implemented icon support, which I fixed up, extended a bit, and
committed to svn trunk a month or two ago. Doesn't support the iMON
LCD's native progress bars though, that would be cool to add support for...
However, yeah, its really more a toy than a useful thing most of the
time (apart from the fact I do use the IR receiver). I'm actually
thinking of swapping out my LCD for my VFD that is more readable at
distance... (I got both to play with).

Its all good, I don't disagree with (at least most of) your rant. :)
