Hi Klaas:  This is what I can recover.  I didn't use the chanscan 
option, but there is one section with the confused channel numbers.


The DVB-T/T2 scans did not find the new QAM-256 transports 
automatically, and a full scan looked as if it would take a long time. 
I'm afraid I let the TV tell me the new frequencies.

"700 Mhz clearance"  ->  DVB-T2 now on 586, 746 and 754 MHz
