They're likely in the order in which it found the multiplexes.  Simply
reorder the lines in the file to whatever you'd prefer.

Google for 'totem channels.conf' to locate the right place for it (hint:
it isn't in ~/).

Never used it.  KDE.  Hideous.

mplayer's handling of interesting transport streams is slightly suspect at
best, IME.  I'd recommend using vlc; 'vlc channels.conf' should do what
you expect.  If your signal is weak, and you drop transport stream frames
(which will manifest themselves as corruption in audio and / or video),
you may find it crashes occasionally in libpsi.  I've no idea why.
