Check mythbackend.log during the timeframe it was recording the show.
If you see IOBOUND errors you've found your problem. I record to an NAS
and occasionaly have these exact symptoms. A quick check of the log
shows the IOBOUND errors. It happens so infrequently I don't worry
about it and don't know the solution. I'm using gigabit with jumbo
frames enabled so you wouldn't think I'd get any errors.
