Is it possible to watch full match somewhere? Or DELA league generally? Is it broadcasted on local channels?
I recommend the website http://www.volleybal.tv --> It broadcast matches of Dutch clubteams or Dutch NT.
Once a week, there is a Match of the Week (Dutch Men's- or Women's League-match) That match is broadcasted LIVE, and afterwards a summary and some interviews are available on demand. Also Supercup is broadcasted, but on the archive is only a summary, I think.
There is a big archive of full matches, especially from NT
