starview if you have Missing channels you can try this.

I have seen a few posts about channels missing when doing a full scan.
Here's a little trick you can try that may help if you're having problems
finding any particular channels or are missing channels:
Try and determine the lowest transponder frequency that you can get a signal on.
Look at the frequencies you already have on the channels saved so far and choose the lowest.
Then in the installation menu select MANUAL SCAN and set that as the frequency.
Make sure you can see a signal and scroll down to Network scan and change to ENABLE with the Right arrow.
While still highlighted, click OK.
Scanning should then begin. It will say 1/1 to start with but should then jump up to 1/?? (the ?? being 2 digits).
Using this method my Starview indicated it scanned 56/56 transponder frequencies as opposed to 48 in Auto scan on one main provider.
I also gained a few extra channels.
The other transponders may have been picked up by scanning other providers.

You could also try using your area's default frequency for the Manual Network scan.

There is a list here - List of Net Id's for Cable TV
the frequency is the 6 digit number, eg, Bath TW, 40970 651000 6952, the frequency is 651.000 Mhz
