latest v31 that you are using and with the new v32 there should be no need
to modify chanid values manually. I have updated the description in the
Wiki https://www.mythtv.org/wiki/Channel_Scanning#Delete to clarify what
happens when channels are deleted.

A possible alternative is Schedules Direct that according to the website
https://www.schedulesdirect.org/regions does have schedule information for
Germany. I have never used it myself but it is supported in MythTV and many
people in the USA use it.

I think I fixed this only in master and not in v31. It is a minor bug that
has been there for years and it does not really give problems.
If you observe this in the new version 32, to be released soon, then please
report again or create a ticket on Github.

Thanks,
Klaas.
