Paul,
I run myself multiple Atoms with Nvidia ION Graphics as frontend and
started to test mythtv v31 on that frontends.
I really want to keep them, as long as possible.
Maybe I can reproduce your setup.
Some questions:
 - nfsv3 or nfsv4?
 - export options on server?
 - mount options on client?

Do you have SELinux installed or is AppArmor running ?

>> if I blow the cache, the frontend cannot retrieve.
Please give me some time to reproduce this setup.

Thx for all your effort on supporting this issue,
Roland
