I've just seen this info posted on the other forum by William-1:
Most Blind Scan receivers work better with a clean data base,
Remove all dead transponders before a blind scan,
If you are still unable to view a tv channel delete the transponder & re-scan with the Blind Scan or add manually
The most common changes made by satellite operators to transponders:-
Audio & Video pids changed = no picture or sound
FEC can change from 3/4 to 5/6 = no signal
Modulation change from MPEG-2 to MPEG-4 or DVB-S to DVB-S2 or QPSK to 8PSK all = no video or no signal,
Symbol Rate changed = no signal
Frequency Changed (This happens more often than you realise even satellite changed for the same feed)
Feed tested fta then encrypted for the live event (check for codes to open)
I hope this explains why you cannot view some feeds,
