If I look at my SchedulesDirect lineup and hover over a channel, is the 
number that comes up the xmltvid?  For example, my local ABC is channel 
6.  When I hover over it, it shows a value of 11794.  Is this what I put 
into the xmltvid column for that channel in MythWeb or the Channel Editor?

Thanks,
