Can PIDS in Service info page be edited?

Some fta HD channels have no sound. I found the PID data in the Service info page not matching lyngsat.
How can you update the entries?

Is the channel list the satellite.xml file? That dose not have PID info. Transponder scan is how the bad data was entered. There should be a way to correct the scan.

FEC wont make a differance... I will look at giving the Bouquets look.... Thanks for the new ideas..
