Hi Robin

Is the TBS6281 not finding any channels or is it that they don't tune? And
what kind of channels are you scanning for - DVB-T or DVB-T2?
I use a TBS6281 with the open source driver and have found it to work very
reliably after patching mythtv with a DVB-T2 patch - see here:

https://code.mythtv.org/trac/ticket/12342
https://github.com/MythTV/mythtv/pull/90

Hopefully one day it will get merged into the source tree.

Lincoln.
