[mythtv-users] Thanks, Comcast, for moving my PBS!

[Phil Bridges]

Comcast moved a few channels on us this past week.  I have re-scanned,
and have discovered them all except for one local independent channel
and a multiplex of PBS stations.  I have scanned using the HDHomerun
scanner, and the channels are there:

SCANNING: 249000000 (us-cable:28, us-irc:28)
LOCK: qam256 (ss=100 snq=100 seq=100)
PROGRAM: 246: 8.3 WGTV kn
PROGRAM: 247: 8.2 PBS Kid
PROGRAM: 802: 17.1 WPCH-DT
PROGRAM: 808: 8.1 WGTV HD
PROGRAM: control

When I use the Mythtv scanner, though, channel 28 shows nothing.  How
can I get these channels back into Myth?
