Every other program used to access the same drive uses the permissions of the mounted folder. If this is not a mythtv bug then I'd consider it to be an extremely undesireable feature!

Since various data and programs use the mounted drive I didn't want to change it to group 'mythtv'. Instead I changed the group of the mount point to 'users':

Please consider taking the time to write something in the wiki. There is 
a page in the Knowledge Base section called TroubleShooting. It needs a 
new page entry!

Definitely an out of left field sort of error that could catch lots of 
peope. I've never been affected but only because my media folder has 
always been the root folder of the drive!
