Bugs in content types

Hello Community,

Hi there,

All was working fine with a video from Youtube, that I used to test my Interactive video (with a Drag & drop exercise), but now my own video is on Vimeo I get the error message that the Video format is not supported.

I have tried mpg and mp4, both the same error message.

Vimeo is set to allow embedding anywhere.

What could be wrong with this video?

Thanks for any help, Roy

PS: 

Hello,

When we enabled surface mode in course presentation, results cannot be saved, because Summary slide is removed in this mode. Teachers want to present the content in surface mode and follow the results of students at the same time.
