@tastymineraler I couldn't agree more. I made a rather extensive summary of the problem here. I must say that I've been really patient with opera, and still given it the third, fourth, and fifth chances instead of just switching to Chromium directly.
Well, if you take a look at the summary I linked to you, there you will find in one place all the different voodoo tricks that you can try in order to fix the problem. I also organized the proposals in four distinctive sections. For me, the option number one did the trick. The recipe in short goes as follows (the instructions how to run the code is given in the other thread as well):
1. Install pepperflash-nonfreeplugin
(and purge all the others)
2. Install the necessary Chrome libs for H.264/MP4
codec
3. Boot your system
4. Volah!
I hope this helps to fix your problem. Cheers!
