That's correct. It is possible with MacOS en Windows and the browsers Safari, Google Chrome, Firefox and Microsoft Edge.

Maybe if it will work with Safari on Linux. Did you try that?   

The Brave browser will do the job on linux.

Hi @spectro, I don't see your message. Did the replys Peter and Hans gave help you?

I am running Debian Stable with Firefox and have no problems whatsoever watching TV on linux.

https://tv.kpn.com/ works just fine here.

The message was meant to be removed. But apparently it is not possible.

Although it is not the first time I have this sort of problem with KPN iTV, and it is very difficult to find the reason, because there is no “changelog” on the website… this time I was able to find a problem with my own sound driver… so after fixing that the streaming started work again.

It is just tiring to have troubles with KPN and there’s always a lot of frustration trying to find solutions… so… 

So you can have an idea, last time I went without internet here, it took a few calls and 3 to 4 hours until someone would recognise that KPN had a problem… 

As least this time I was able to find it here, so this post was rendered moot.

Thanks for the attention anyway.
