Many streaming video applications use RTP which uses TCP/UDP ports 554. Blocking these ports should prevent most of the undesired traffic, though I believe some applications are capable of using other ports as well.

Imran,

Most streaming video these days is tunneled through http TCP 80 making it very difficult to filter with ACLs or NBAR. Your best bet is using a proxy server with filtering capability. An example: http://www.bluecoat.com/products/sg
