Hello, Just compiled the latest again, but still no difference. kaffeine doesn't see any source in channels dialog, two devices are in 'Configure Television' dialog: DRXK DVB-C - device not connected - as Device 1 and DRXK DVB-C DVB-T as Device 2. Concerning the last one, no source is selected, as I am in Romania, which is not in the list scan_w finds nothing. What should I do next? Regards, Mike.
