Scott (and others having issues playing ISO files over storage groups) -

Digging up an old thread to try and help some folks...

I too was having issues playing back ISOs that had worked fine prior
to migrating to storage groups (that were also decrypted).  I
submitted ticket #9844, and Mark was quick to find an issue with case
sensitive file extensions.  After changing all my files that DVD
Shrink created with capital ".ISO" down to lower case ".iso", the
majority of them played again as expected.  I have a few that still
produce troubles, but I think that's a separate issue.  Anyway, just
wanted to share.  Here's the ticket for more details -
http://code.mythtv.org/trac/ticket/9844

As a workaround until the case sensitive stuff is actually backported
(it's already been fixed and applied in current master which is
pre0.25), I've created a script which I attached to the ticket that
you can run which will find all files with a ".ISO" extension and
rename them to ".iso".  You then need to scan for changes within
mythvideo.  Worked for me at least.  Here's the link to the script -

Thanks!
