Here’s a wiki dedicated to opening up the MovieBeam player, a Linux-based set-top-box recently obsoleted by the demise of the MovieBeam service –
The MovieBeam service was a unique system for delivery of movie rentals to the home. It was based on a set-top-box using a special over-the-air data receiver, a hard drive and secure playback software. The terrestrial broadcast data transmissions would continually “beam” new movies and promotional material to the box where they would be stored for subsequent playback. The system would keep somewhere between 80-100 titles on the hard drive available for instant rental. While some of the hardware is quite specialized, the underlying system runs a variant of the Linux operating system and theoretically the box can be used for other purposes than its original design.
Purchased by Movie Gallery in early 2007, operations for the MovieBeam service ceased on or about December 15, 2007 and their website went down shortly after that. Inquiries with what was left of customer support regarding what to do with the player were met with “you can do as you please with the player.” This wiki is intended as a repository for information regarding hacks and exploits on the MovieBeam player in the hopes that a few of them can be saved from a landfill.
