[mythtv-users] Backend hangs when about to watch live-tv

Hi all, i have been searching google for this but I still can't figure
this out so any help would be appreciated.

Problem: When leaving the backend for a day or so and then trying to
watch live-tv from the frontend it hangs. It has been running fine up to
that point since it's gladly scanning EIT every now and then. When I try
twice I get two different errors, first time with the frontend reports
"error displaying video". Second time the message is "Cannot connect to
backend, is it running?".

I have set the disk to spindown after 1 hour with "hdparm -S 242". Is it
 possible that mythbackend dislikes this?

The mythtv storage and the mysql database is on different devices so a
EITScan shouln't spin up the drive. Is that correct?

Regards
