You can scroll down to "Free RealOne Player" and download that. That should let you open .ram files and view the video clips.
You can also view the USA Big Brother on this page by looking in the top right! (just incase you suffer from BB syndrome!)
Anyway, so if you download the "Free RealOne Player" link, it should be ok...
Let me know if it works!
Good Luck!
