Hi,
I tried to search but did not find this mentioned. I enabled EPG scan, and started getting garbled recordings. Looking at the recorded 00*.ts files, they contain ASCII text from EPG. Problem solved, set the background updates to 0 again.
This is with 1.7.13 and 1.7.14, and two TT full DVB-C cards.
I think the same happened with earlier generations of vdr, I vaguely recall disabling the background scan because of this years ago also.
Regards, Jaakko
