[mythtv-users] Log filling with "Poll took an unusually long time"

[Robin Gilks]

Over the last 2 days I've now recorded this message 24000 times in the
backend log from the analog recordings from an HVR2200 tuner on
/dev/video0

The messages seem to be on average about 3 seconds apart during a recording.

Anyone any clues?
