Hey,
In the past couple of days mythtv-frontend-0.18.1-116.rhfc4.at has
locked up on me 3 or 4 times during playback of recorded shows.
This is the first time I have seen this behaviour and each time I was
attempting to playback recorded movies at least 2 hours in length..
The shows were recorded with ivtv4.0
The only recent change is starting mythfronted from an init script at
boot. In an attempt to rule that out, I stopped mythbackend and
restarted it as my regular user and the bahaviour persisted.
Any ideas?
