After another reboot of the Mac the problem persisted. Then I tried some other MPEG4 titles and they played fine. Back to Ocean's 13 and now it plays fine. If I switch the fMP4 setting back on they fail again, so that seems to be the issue. Oddly, after switching the fMP4 setting back off a second time it takes several tries before playback begins to work.
What's the downside of having "Prefer fMP4-HLS Media Container" disabled?
