Matt,
Thank you. Well at least there's consistency here. The only backend event your log shows being received is the RECORDING_LIST_CHANGE event and after that, the event handling thread appears to hang. Michael's backend log shows that the LIVE_TV_CHAIN UPDATE events are being generated by the backend so I know that's working.
There has to be some race condition on mutexes or something of the sort that blocks the event handling thread and that's what I was looking for by reading the code.
Since I now have two traces from two systems that show that after RECORDING_LIST_CHANGE is received event processing stops I'm going to build a dongle that does nothing for that event to determine if something in the RECORDING_LIST_CHANGE processing is causing the thread to hang (even if I never see the last debug trace that indicates that this case in the switch is selected).
I'll try to have a dongle for testing available tomorrow.
Thanks again.
Cheers...
Sergio
