I want to watch USA Network videos of my favorite shows but they don't come up. Do I need to purchase aftermarket software from the app store or is there something I can do to watch them?
It looks like the videos on usanetwork.com are encoded with Flash.
There is no Flash on the iPhone (yet), so you cannot view those videos on your iPhone right now. There is no app that you can download that will allow you to view them, either.
