Hi Dave,
If your asking whether I would update the video plugin to have a nice default image as opposed to no image, the answer is yes because no thumbnails at all looks a bit weird on the page.
However, as the original video plugin works just fine and has thumbnails (which is what is happening on my installation), the answer is no. I'm quite content to use the original video plugin and wait for the fix (and, if it has a nice default image, so much the better).
Besides, I'm thinking you guys have enough on your plate at the moment with Oxwall 1.6 : )
Cheers,
Allen
