How can a user recognise this situation ? Eg QPSK modulation in
channel list instead of QAM64 ?

Scan each frequency means:
1. add all transponders from "w_scan -x" into mythtv and scan existing
transponders
OR
2. you have to add all channel information from "w_scan -X" into mythtv

This means modifying the netword id in mysql and NOT do a rescan ?

How can a user recognise this situation ?

The pefect solution would be "talk to you provider, they should fix
it", right ?

Thx for your help...
