Ahhhhh, I see what I did.  I have three zap2it lineups, an analog (for the
PVR-500), a digital with everything but the HD channels (also for the
PVR-500, but the s-video input), and another digital with only the HD
channels (for the firewire).  I divvied up the digital channels among two
feeds to reduce the chance of conflicts, since the s-video and the firewire
both use the set top box's tuner and Myth doesn't know that.

So when I added the QAM, I used the third lineup, but I used some XMLTVIDs
from the analog lineup, not realizing the significance of that.  So I can
only use IDs from the lineup assigned to the QAM input, sounds like.  So
I'll have to add the SD channels I get over QAM to the lineup that currently
only has HD channels.  Is that correct?

Thanks Geoff.

btw, I think I manually inserted some of those XMLTVIDs when I was
experimenting.
