Yes. That is a reason to have an NFS mount (all MythTV
"recorders"--including transcoders--need to be able to write directly to
the file system, so you can use NFS to make that file system available
on a remote system).
However, a properly configured NFS mount is usable for /both/ playback
I.e. there's no reason to use NFS for transcoding but not use NFS for
playback. Therefore, you don't need to force MythTV protocol streaming
from the backend for playback. Just let it use the NFS-mounted file
