I couldn't get that file to fail to play.
NeB are you using a whitelist?
I suspect your issue is probably related to hdmi cable, but having a whitelist set up (allowing lower resolution/refresh rates to be chosen) will make it less likely you'll hit issues.

The debug log would be useful to see exactly which hdmi is being chosen.
