Can't play videos while in Cubase?

When I have Cubase loaded I cannot play online videos (such as YouTube), MP4 files, or MP3 files. Is there a way to be able to run both of these functions at the same time? I’d like to do so in order to reference songs and tutorials from the same computer while I mix.

I’d try try that option “release driver when app is in background”, or something similar. I don’t recall the exact name.
