How do I block streaming audio and video?

I am running a small network of about 15 users through using a verizon wireless PCMCIA card in a linksys wrt54g3g-st router.  I am having a lot of trouble with the users streaming audio and video, and also downloading videos.  My router allows for port blocking and website restrictions.  I currently have a few sites blocked but I'm still having trouble.  Does anyone know which ports I need to block to stop all streaming audio and video?  Also is there anyway to block media downloads?  Any help will be greatly appreciated! Thanks to all in advance!  Also I am remotely managing the router through port 8080 and I'm using DynDns.org for DDNS.

I think you are pretty much doing everything you can with what you have, to truly block and stop what you want you will need a third party solution, that is made specifically for this...many sites use port 80 now for streaming their audio and video.
You will need a solution that will and can tell the difference in the media being pushed.

I agree with the previous poster.  Or get a small Cisco router that can do NBAR and police it there.

Agreed with peralesa.

While you can block a few default ports (tcp/udp 554 for rtsp and tcp/udp 1755 for mms), there is simply no guarantee that you can catch all. Most streaming protocols are able to use non-default ports, and a lot of streaming traffic is going over tcp port 80 (web) these days.

You need something that is able to look deeper than just port number in order to classify/recognize (and then block) streaming media.

You'll have to get content filtering service.  You'll need a soho firewall with content filtering to accomplish what you are looking for.  Sonicwall works well.  You might look into TZ150 with content filtering option.
