Going from memory here, but iirc, you had a setup with an antenna feed 
and you changed to a Comcast cable input. Then you scanned, got some 
usable channels but cannot get the schedules direct listings to come out 
right.
I presume from what you have stated that you created a  new lineup.
I also presume we are talking about .22-fixes or trunk.

What you probably missed is one of a number of things, one of which may 
actually be a bug in mythtv-setup (which did not exist prior to say SVN 
21000)

First: go into mythtv-setup, and check that the you have us-cable set 
for the tuning basis, for the HDHR tuners. (Remember, they were set to 
broadcast).
Second: make sure that you have the correct lineup selected in the 
'Video Source' settings, including setting the correct tuning basis. 
(Not broadcast!)
The lineup selection settings may not 'stick'...I am not sure if this 
was my operator error, or a mythtv-setup bug, but when I recently added 
a new ATSC tuner and third lineup, and then checked my other tuners, 
mythtv-setup changed the lineup on the others, to the new third. That 
is, it came up with the third lineup as the 'new' default for the second 
tuner, NOT the second lineup previously set for that tuner. This meant, 
for example, that I was about to attempt to record from an analogue 
tuner using a digital lineup...(Yeh, good luck with that Geoff!).

Lastly, on the Input Connections page, there is a second page for each 
connection. MAKE SURE THAT THE TUNER GROUP IS SET TO GENERIC!

Since I had been installing a digital tuner, but things got bent, I 
ended up with a tuner group of HDHR, for an analogue tuner (PVR500), 
Tuner groups are supposed to consist ONLY of tuners of the same sort (so 
that myth is able (entitled) to choose any one of the group, to tune 
channels within the group's range). I suspect that this was an artifact 
or result of the other problem. I did not set out to change my analogue 
tuner setup, but the lineup got changed to a digital lineup, and I 
suspect this forced a change in the tuner group....NOI SURE...but things 
ended up not correct.

I suspect that your problem is either the second or third problem, most 
likely the second, since you say you get listings, but they are wrong. 
This means there is a lineup, but it is not correctly matched with the 
channels you get.

If these pokes and prods do not work, there is always the channel 
editor. Go into live TV, change to a channel using this tuner, determine 
what program is on (zap2it.com/listings is useful to figure out that 
what you are seeing is on channel X), then press 'E' and fill in the 
call-sign and xmltvid data. If you hover you mouse over the channel 'X' 
logo/name in the leftmost column of the listings page at zap2it, the 
xmltvid is revealed as part of 'number=12345' in the status line, 
showing the URL link for that logo/name etc. (Schedules Direct has the 
same info, but you cannot look at a live guide listing at the same time).

mythfilldatabase --refresh-all when done.

Good luck.

Geoff
