Bluray ISO plays on Server machine but not on client machines

[Ranger One 0]

Have some Bluray Concert ISO's.

MB Theater installed on Server Computer as well as client computers.

 MB Theater settings the same on all machines with same versions & settings for LAV Filters.

MB Theater plays the ISO's  fine on Server machine, but not on client machines. 

Checked MB Theater logs on client machines:

Status error: 5 unable to open mount file (ISO File file from Server)

InternalDirectShowPlayer: error mounting iso (file from server)

Unable to start mount for (file from server)

 

Any ideas as to why this is happening?

 

If anyone has found a way to convert concert Blu Rays to .mkv with chapters & song title info I would like to know!

 

Thank's!

Did you define the library with UNC paths or setup path substitution so that the other machine can access the media location?

I've always used UNC paths. Tried the substition option, same problem, MBTheater on client machine couldn't mount the iso.
