The pic above is my screen with the you tube video in it.
Congrats. Looks like you figured out how to post a photo in a forum thread! You will find that this is a very useful skill when posting a thread or replying to a thread question/issue. Sometimes a photo/picture is "worth a thousand words"!

Thanks Nick, but it's a VERY slow learning process for me! LOL
it's not a fix, however once you go full screen (shows up 1/2 screen size) pause the video, then click play and it will go full screen. I'm having the same issue since the last el capitan update.
I have not been able to find a fix for this yet. Youtube has been notified of the problem. Good luck!
I didn't suggest it was either once I understood the issue (see my most recent post in this thread -- I pretty clearly said it might be an error on YouTube's end, or a glitch in El Cap.
In any event, I'm glad it has been resolved. Happy Boxing Day everyone.
Just got done checking out a few videos on You Tube and suddenly realized that they were in full screen! Don't ask me how though!
