Keep complaining about it to them. That will eventually force them to change the policy.
what he said.I'd also see what their premium members get at NFL.com and inquire with them. Remember CBS does alot of webdesign work for NFL.com and they played the NCAA games over the web like TV/video. They can certainly handle this from a technology standpoint.
NFL.com also offers alot of video highlights from NFLNetwork on it's website like replaying a Rich Eisen interview for example.
NFL Network's website is less than stellar. I figure there's gotta be some plan there.
