  My first thought would be see what other cron jobs may be running at that same time (or starting somewhat before it) - it could be some other job that is using a lot of resources, and thus starving mythtv (for example, if there is a job that traverses the entire filesystem looking for things to clean up, that may consume enough of the IO to make mythtv have issues).

Possibly look at /var/syslog or elsewhere to see if there are any messages indicating issues.
