On the backend what are your folder paths in your video storage group? And what is your NFS mount point / path?
On the frontend, is the NFS share also mounted and if yes what is its mount point / path?

Mythfrontend will check the storage group folders directly before asking the BE to stream at which point the BE will check the storage group folders. It is possible that mythfrontend can find the file directly if the identical mount points exist on both the BE and the FE, but perhaps the user running mythfrontend does not have permission to read it.

You are also getting these which may or may not be related but probably need to be sorted out. Does your BE recording drive also contain your OS and / or database?

            The response to MYTH_PROTO_VERSION was empty.

            This happens when the backend is too busy to respond,

            or has deadlocked due to bugs or hardware failure.
