Movies and TV Xbox Family Sharing

I attempted to follow your link and it would appear that it is no longer available

Unfortunately, what you're seeing is correct. Currently there's no way to share video content purchased/rented from Microsoft Movies & TV or Xbox Video between accounts.

I would definitely take a look over here, http://moviesandtv.uservoice.com/forums/225596-microsoft-movies-tv-feature-suggestions and
post your feedback and/or upvote on of the already suggested items. That way it's sure to get in front of the correct folks.

Party mode was also in zune but everyone in the party had to rent or buy the movie or tv show put that same thing in xbox video but let the host share it with the party. Microsoft was about to have game sharing since we cant share our games at least let
us share our movies in our video apps

I also found this for you: Use Family Safety settings to control Hulu Plus access

You can use Family Settings to control which movies and TV shows can be watched with the Hulu Plus app. For example, if your Family Settings restrict viewing of R-rated content through your console and you select a restricted program to watch, you will be
prompted to enter the Family Settings pass code.

For more information about how to restrict movies and TV shows using a pass code, see Xbox 360 console parental controls.

I never utilized it so I'm not to sure...unfortunately a lot of my friends don't share movie tastes....live stream and /x/ were my preferred choice but hopefully it returns because it sounded like a great feature that could be great for a family separated...
Can you say family movie night
