I saw an old topic about this and was going to reply there but it asked me to start a new topic as it was quite old.
I am using OPERA 51.0 and have an awful time playing videos from any site. Most times I just get an error or it will start playing then stop half way through and say it's not available in my country. You Tube seems to be OK but that's about it. This is very frustrating. To see the video I have to open Chrome. I like the features in Opera but shouldn't have to open a different browser to watch videos. Any help appreciated.
