Some of the recently uploaded videos aren't working - there's no thumbnail and when you click on them, it says 'No video with supported format and MIME type found'.  I've tried it in Firefox and Microsoft Edge but both get the same problem.

Thanks for the head up Donnn, we'll get this sorted.

That applies to the last 70 videos uploaded. Everything was fine until sometime yesterday afternoon after which every single video uploaded is corrupt and cannot be played. I am using a different browser to donnn which is Chrome but this makes no difference.
