as you may be aware some areas lost all channels but have found a way of getting them back.

I found em using tivo sub box.
Goto settings diagnostics...all the digits...
Scroll down
It will say tuner 0
603250
Qam 256
Manually add this tp to kv with sr of...6952

Goback to tivo. .
Theres two more tuners...
Add em.
6952

Goto kv...manual scan
On the 8tps these come up "fail"
Try one of the 3 you just entered. ..
For a start it will scan for longer...
One or two may fail.
I think it only has to find one channel and your tp list comes up "Litchfield"
I then auto scanned again.
It found shed loads.

a very well done to him.
