Your log shows you trying to scan ATSC channels. Did you select DVB-T?
Yes, I definitely selected DVB-T.
I just tried scanning with WMC. It had trouble identifying the tuners. I did a manual scan which worked OK. I think I remember this happening before.
On MC, if I use Settings > Configure to set the tuner type to DVB-T, when I select scan, it still shows ATSC and I have to select DVB-T again. If I look at Settings again, it is still set to DVB-T so I assume that setting is working. Could there be a problem with the scan tuner type selection?
I have run another scan, definitely on DVB-T. See what it says.
Nick.
