Yes, just as you predicted. Disabling JavaScript did cause a lot of issues. I could not even log in the site when JavaScript was disabled.

I'm afraid I'll have to skip Opera for this site, unfortunately.

@leocg

And it there anything I can do about it - do get it working?

Thanks for taking the time to help l33t4opera!

Don't know if you had a look at the screen-shot I posted earlier. Here it is: https://s32.postimg.org/vx1bl0ojp/opera.jpg

I think I'm doing just as you told me. However I have no idea why it isn't working.

@l33t4opera Am I doing it wrong?

@l33t4opera

Hi and thanks for your suggestion. However, unfortunately it didn't seem to make any difference.
I tried both [.]play.tv2.dk and [.]tv2.dk

So I should just say as TV2 support says, and just use another browser?

Yes, I just tried uninstalling Opera (also checked "Delete my Opera user data".
Installed Opera 38 again. Same problem.

I get the message allow video to be shown in full screen too, and there was the option "remember my choose" unlike with the "this page wants to disable your mouse cursor".

And it still works just fine with Firefox, Chrome and IE.

I even contacted TV2's support, and they just replied that Opera wasn't supported at their service. And asked me to use another browser.

Anyone?

It works just fine in Chrome, Firefox and IE.

Its only in Opera I get this annoying message.

Oh OK. I thought it was a solution to my problem.

However seems like no one has a clue
