Just guessing: 2 possible answers.  1. It looks like the mount on the 
server is exclusive and no-one else is allowed access while the server 
'owns' it.
2.  You, as a user on destiny, do not have permission to actually read 
anything mounted on mythtv. Maybe add yourself (piers) to a group on the 
server and on the client, and give the group access rights to 
mythtv:/media/cdrom.
