Thanks for the log file.
There is something puzzling in the log. Was the log produced during the process of scanning, and only scanning, for channels?
I see in the log intermixing of logging entries for scanning and playing channels.
During scanning, you aren't supposed to be able to start playing any channels (you should not be able to double-click any channel entries). Did you wait for scanning to finish and click OK buttons to exit the scanning window? During scanning you can sometimes briefly see a program being played, but that usually only lasts briefly, until the scanner moves to the next channel.
