Off-road did make it use YouTube. Thank you very much for the help. I just prefer it uses YouTube instead, as its quality seems to go higher than the default player, but it's understandable that it plays like it does to save on RAM.

I have Opera mobile v.27 and I was wondering if it's possible to make it so that when I open links to YouTube videos or click a video, it opens the app and plays them as it does in Opera Classic.
