That was an intermediate step, yes.

Another config was to only have a EIT-only-source in mythtv (mythtv not
knowing about the external grabber) and running the grabber "manually"
outside, then doing a "mythfilldatabase --file ...".

But I assume that would cause the same conflicts ... ?

I still haven't fully understood the "--update" option for
mythfilldatabase, btw.

I somehow assumed such conflicts triggered, yes ... especially when
editing the channels I noticed many duplicates etc.

phew ... quite some task again. I will give it a try, but maybe it will
take me until weekend to be able to report back.

Thanks for the howto ...

btw I still have the issue that tv_grab_eu_epgdata doesn't deliver
correct output ... as mentioned in another thread here I reported a bug
to gentoo.org already.

So currently I can only run the grabber on another box ...

I will read through this as soon as possible, thank you!

Right now I am somehow happy to have a somewhat working system up again,
as there are some recordings I would prefer not to miss this evening.

Greetings, thanks for the support, Stefan

ps: is there a way to "speed up" getting eit-data in or is that just a
question of "just wait for it" ?
