Sorry, that was a premature assessment.
For testing I edited one of my DVB-T channel entries and changed it
from B8C34D34G4M16S0T8Y0 to B8C34D34G4M16S, which was wrong - I should have
stripped the 'S' as well. After correctly changing it to B8C34D34G4M16
the error did not occur any more:

Apr  1 11:57:32 vdr2 vdr: [6861] switching to channel 21
Apr  1 11:57:52 vdr2 vdr: [6885] changing transponder data of channel 21 from 562000000:B8C34D34G4M16:T to 562000000:B8C34D34G4M16S0T8Y0:T
Apr  1 11:57:53 vdr2 vdr: [6861] retuning due to modification of channel 21
Apr  1 11:57:53 vdr2 vdr: [6861] switching to channel 21

So I'm afraid I don't know why you are getting this error.
