[mythtv-users] Lost a bunch of channels on HDHR prime with comcast

[Monkey Pet]

Within the last week, I lost channels above 750.  I can tune it using a
standalone cable box, but mythtv can't tune it.  I tried reload the channel
lineup from schedulesdirect but the issue still persist.  I am using the
HDHR prime with cablecard.  Everything was working until about 2 weeks back
and then I noticed that recordings started to fail.  The channels under 750
seems to be working fine.

Mythbackend complains about a invalid virtual channel when trying to tune.
 See below.

Can someone tell me how to debug this?
