Thanks to a suggestion from solarbird, I wrote to Tourisme Montreal and asked if they had the promotional video in a form I could download from their web site. They pointed me at the file. (I'd point to it, but from the address, I am not sure it's meant to be publicly available.) After a bit of fiddling around, I was able to figure out how to save the video to my machine locally. (It wasn't as simple as right-clicking the video.) Then I played that file, and lo and behold, it will repeat without further intervention by me. Assuming we can get it working with the screens in the suite, this should work, and add some needed color to the room.
kproche, it looks like we won't need the portable DVD player after all.
