I believe this is usually done with a SAN via iSCSI, in the case of
Ethernet. You'd basically be accessing the host as a block device
rather than through an NFS or Samba server. Streaming 4K uncompressed
video over a Samba network sounds like massive amounts of pain waiting
to happen.

Also, I wouldn't be playing the video in MPlayer. I'd be sending raw
RGB to a SDI output device so I could watch the result on a proper
calibrated display / projector. That's typically how it'd be done in a
proper post facility.
