[mythtv-users] one single channel stops working (DVB-C, both LiveTV and recordings)

[Joachim]

@Nick Rout: thanks for the suggestion. But unfortunately, running the 
database repair script didn't solve this issue.

@Jan Schneider: glad to know that I'm not the only one with this problem :-)

To help debugging, especially reproducing the problem for those not 
living in Germany and thus not suffering from this issue, I made an 
example recording available for download -- see
