This is a great new site that offers a podcast aimed at language learners. It's informative about Dutch culture and each podcast is nice and short, so it's not overwhelming.
This is a site that presents streaming video of Dutch television programs. The idea behind it is to let you catch up if you've missed an episode and they delete episodes promptly--so if there's something you want to watch, make time to do it before it disappears! Watching television programs can be very entertaining, but linguistically I'd say that it's one of the most difficult ways to practice, since everyone speaks so quickly and there is often little context.
Omroep is the Dutch equivalent of the BBC or of NPR/PBS. This site presents a somewhat bewildering array of material, including audio and video.
Podcast.net indexes podcasts on many different topics, but this page lists podcasts associated with the Netherlands and Belgium. Note that not all of them will be in the Dutch language; some are in English, though it's pretty easy to tell which. Also, podcasts have a tendency to come and go, so you might fall in love with something and find that it's never updated again.
This website presents a list of Dutch films available on video or DVD. They are offered for sale but you may be able to find some of them on other services such as Netflix. Most are in Dutch but note that a few are in English.
This is the Dutch-language site for the equivalent of NPR. They offer both streaming audio and podcasts/downloadable content.
This site offers streaming audio of a Dutch radio station, however, depending on when you tune in, it may be all music.
