I know that a lot of people are doing exactly what you are with NFS 
without the problems you're experiencing ( 
http://mythtv.org/docs/mythtv-HOWTO-22.html#ss22.10 ).

Do you have the same user (= same uid, username isn't important) running 
the backend on both machines?  If not, it might be a problem with 
permissions.  Or, if you're running the backend as root, it may be a 
permissions problem caused by NFS's root_squash.

Not required.

To get this behavior, you have to use the NFS approach you tried above.
