QuickTime captions menu greyed out

Question

I created closed captions using MagPIE, and placed the captions in the same file as the base media. I've selected "Show closed captions when available" in Edit/Player Preferences. But the captions do now show up and in View, the menu for Show Closed Captioning is greyed out. What is missing?

Hello there
Export Settings
I used codec settings and export settings you had set in the project you shared for MXF OP1a embedding to closed captioning. Embedding to MXF -- I could see 608 and 708 closed caption in the resulting exported MXF in PPRO CS 7.1. In "Export Settings" via File-> Export-> Media, I also tried other Video Codecs under Video to see if this could make a failure to embed closed captions into MXF -- but I didn't see a problem.
Preferences to Import Closed Captions
Nothing special needs to be done for PPRO to import closed captions embedded in MXF or MOV files, if the caption data is there, and the user has "Include Captions on Import" checked under Preferences-> Media then that should do it.
PPRO Monitor Settings to Display 708 CC
One thing to check, is in the Source and the Program monitors -- see if under the wing menu "Closed Captioning Display" "Settings..." is set to CEA-708 -- if it is set to 608 or to a different service not matching the 708 service your CC data is associated with, then you will not see 708 closed captions in either monitors if this is not set right.
Other OP1a MXF Embedded CC files
You also could post the other two OP1a MXF files that you see are giving you a problem, not showing closed captioning in PPRO CS 7.1, and I can look at them and see what I see.
Thanks, as always, for following up.
