We are in the process of constructing a site that will allow news outlets to download and edit content. In beta, we've had a little trouble finding a codec that would fit into the broadcast news stations workflow. Deadlines are tight, and if our content isn't easy to use, they just wont use it.
If your a news editor, or have worked in that field please take a second to take our poll about news friendly codecs. It would help us out allot.
