[mythtv-users] recording failed .. why?

[Paul]

I have been running mythtTV for several years and recently I have noticed some recordings 
fail, only some
So I cut some of my backend log file:

Hopefully someone can tell me what to look for to determine the cause, as I can only see 
these lines which don't really help..
