Have to use an NTFS formatted drive to take a DCP master of a film to a cinema for a test screening. The cinema says they need NTFS. I somewhat doubt that's really the case but one never knows what oddities might surprisingly be the case for obscure hardware like cinema servers. I used a windows computer I could access in the end because I couldn't figure out how to get this to work but I was trying to acquire the capability for future such cases so I wouldn't need to do that next time.
