I've made some time ago a chrome extension for myself for playing belgian vod.
You can easily get the data-filename and data-application from both vier.be and vijf.be by using the video id from the sites like using 2413625 from the url http://www.vier.be/comedykings/videos/humos-comedy-cup-2016/2413625,
You don't need the login details for both sites anymore.
Ofcourse you can replace vier.be by vijf.be, but it doesn't matter because, the video's are on the same server, so they work anyway.
I hope this helps you, good luck and keep up the good work!
