It is not youtube that changed anything. Its Apple Firmware that broke it. So Apple should fix it, not Youtube ?!!!!! Can you imaging imbeciles releasing major firmware release worldwide to break functionality of apps ?! The "trailers" app is also not working anymore.

It seems that this going on for almost close to 10 days ! From the very minute the Firmware 7.5 was released.
