Mythtv uses chanid as the unique identifier. Channum can actually be
anything you want. XMLTVID is the unique external identifier used by
Tribute Media/zap2it and Schedules Direct. So the mapping is really
xmltvid to channum.
Basically, you have to discover exactly what channel is playing on any
particular chanid. Comcast probably has an online listing of channels
which you can match against your SchedulesDirect lineup or at zap2it.com.
Where you have duplicate xmltvid's on different sources or cable
channels, you will have to differentiate them by tuner priority
(source), since Comcast is likely delivering the same stream, in
different definitions. IOW channel 104 is a standard def version, while
608 is an HD stream, of the same external channel. Worse yet, if you
have an antenna, that same channel will be available through a third
source. You may want to split your lineups so that, for example, the SD
channels are only available in one source.
You can change the channum descriptions for each, so that your program
Guide shows each differently, but tuner priority is the only way that
myth will differentiate the streams internally (I may be wrong about
that but I don't think so). The guide will internally6 see them as the
same group/set of programs.

Please let me know if anything I say offends you.
I may wish to offend you again in the future.
