Problem partly solved.
My problem with the Opera VPN looks like it is in the choose of the Plug-ins in " Menu>services>websites>plug-ins>Start all plug-ins ( or start all known plug-ins, advised by Opera ) . Opera's standard choice is " click to play ". So every time when I start the VPN ( Spain-Netherlands) I have to change the adjustments . This is a small problem.

Up till this moment I haven't received a satisfied answer solving this VPN-problem.
For example, I am connected with NPO's -uitzending gemist-, without VPN, no problem. Then I make the connection via VPN , I receive the advertising video's, but the main video don't appear. Under " Element controleren " ( Cotrol+Shift+C )I can see that the system stops at " video-player loading " . For my this is clearly an Opera problem . What is Opera doíng to solve this and in what time ?

Repeat: ( see 25 November ) I try to watch Dutch TV from Spain with Opera VPN. When I have contact with the site, f.e. Kijk.nl , they show my the advertising video's but when they switch to the main video I get the message " The video you are trying to watch is currently unavailable " . I have the same problem with the other sites of Dutch TV's

I have the same problem, sometimes it looks like the system is working, but only for the advertising video's.
It looks like the media player can't make an connection. I have tried to make the connection with "Disable non-proxied UDP" disenabled as with enabled.
