YouTube integration in HD

Hey guys,

I want to integrate YouTube videos and they should be automatically played in the highest resolution (most of the time 720p HD). Is that possible or does it depend from the quality settings of the viewer?

I put in here for example the YouTube video link + “&hd=1” which should set it to 720p. But that doesn’t work.

Thanks in advance!
