[mythtv-users] MythTV stops/doesn't start recording

Since a few day I have issues with MythTV sometimes either stopping a  
recording after a short time, or not even starting a recording. The  
recording appears under recordings, but either it cuts off after a few  
minutes, because it's only a few MB large, or the file isn't found at  
all.
The backend logs show nothing but a running recording. This is a log  
example of an empty recording, i.e. one that doesn't even create a  
recording file:

channel 1104

As you can see, nothing suspicious, it looks just like a successful  
recording. Syslog is only happily logging cronjobs and network card  
messages too.

The only changes I have done to the system during that time, is  
keeping up-to-date with the Mythbuntu weekly 0.21 fixes.

Any help is appreciated. WAF has decreased a lot already.
