LR CC: videos play on one iMac, not the other

Having trouble getting videos to pIay in LR CC on one iMac but not the other.

To test, I shot four 5-second videos on my iPhone X, two each with the standard Camera app and the Moment app — one at a normal frame rate, the other in slo-mo.

On one iMac everything is just fine — I was delighted that Lightroom CC could deal with the slo-mo!

On the other iMac, the four videos appear (with thumbnails) in the Grid view, but in full-screen Detail view, only one (the slo-mo version from the Moment app) plays. The other three open in Detail view without a thumbnail and with the playbar either at 00:00 or slightly advanced — regardless, everything is frozen: can't move the playhead, no thumbnail, no image, no play.

Both iMacs running High Sierra [10.13.3], both running Adobe Lightroom CC [1.2], both have QuickTime [10.4].

On the iMac that won't play the videos, I've uninstalled LR CC, restarted the iMac, and reinstalled LR CC, but those steps didn't address the problem. 

Any suggestions would be much appreciated.
