Interesting - thanks fpr the tip. The firmware shows 5.0.0.0123 from Aug 12, 2014. None of the host component info has been updated from 25 June, 2014 either. Not sure what Rogers was doing to my system then - the PVR definitely got rebooted three times in two days (Sun+Mon). After about two days of weird behaviours, the PVR has settled down and seems to be functioning normally again (caller id back, all channels back, recording seems to start and stop on time).
