Yes, I get this too, but there's no noticeable difference between when the button says "... default ..." and when it says "...

On the YouTube HTML5 page, do you get a "What does this > browser support?" section? If so, what does it say? Of the six boxes there, I have ticks (?check marks?) on o - HTMLVideoElement o - WebM VP8 I have exclamation marks on all the others, namely o - H.264 o - Media Source Extensions o - MSE & H.264 o - MSE & WebM VP9 . It's frustrating that "HTML5" isn't mentioned in that list of six. I'll take your tip and try rebuilding with gstreamer enabled. Thanks! -- Alan Mackenzie (Nuremberg, Germany).
