The Dutch politics broadcast is usually no problem when viewed via the Nederland24 addon. The bigger problem at the moment is that all politicians are on holiday until September 4th, so testing that is a bit more difficult.
I have a beta version of a so called "Tweede Kamer" addon, based on the Nederland24 addon. It incorporates the other "Tweede Kamer" channels,
like "Troelstrazaal" and "Thorbeckezaal".
During holidays they are broadcasting dummy streams, so testing is not a problem.
