When getting access denied I started to wonder if I'm trying to watch the wrong channel. Found another called "Viasat Film Family" (Service id: 1195). But same result. Access denied.
So I tried out the Canal Digital and now it works. I get an video, it's just very laggy and stops to buffer all the time.
