I guess I'm in the minority here. I've tried XBMC (on xbox, mac, and
linux), and while it's not bad, I find the interface non-intuitive. The
menus are fine (and pretty), but the video/audio controls are not what
I'd call well thought out (at least the default mappings). I may be
missing something.
Of course, I've been running Myth for over 5 years now, and I haven't
found any frontend I like better (including MythMusic, which seems to be
extremely unliked). To each his/her own...
To stay on topic, I'm seeing channel changes of about 1-2 seconds after
my IR blaster script finishes - the script adds more time, and I've
stretched out the intra-digit delays to make sure I get solid changes.
I can't remember the last time I had a failed channel change, and that's
the most important thing. Of course, as others have said, livetv is
maybe a once a month thing (if that).
