Hi Robin,

Are you accessing the ISOs via storage groups?  There were some issues 
at one point accessing encrypted images via storage groups.  I *think* 
those issues were fixed, but to be honest, I don't remember.  I've only 
ever really used decrypted images when I've used them at all.

It doesn't matter which libdvdnav and libdvdread libraries you have 
installed, MythTV uses its own copies.

Richard.
