The MPAA is pressuring the FCC for the authority to cripple recording devices using so-called "Selectable Output Control" (SOC).
Basically, SOC would enable Hollywood to actually shut off the video outputs on your cable box, DVR, or other recording device when particular movies or shows come on. When the movie's over, the outputs might turn back on. Your devices would dance to Hollywood's tune.
Most cable boxes and DVRs already include Digital Restrictions Management (DRM) and operate using proprietary software -- both of which we need to work to eliminate. But just because many of these devices already use DRM, that doesn't mean we should let Hollywood and the FCC keep adding more. This new form of control would take even more freedom away from people using those devices, would restrict people using free software like MythTV to watch broadcasts and record them, and would set a dangerous precedent elevating Hollywood's desires over the public's freedom.
There's a link in the full article to submit a comment to the FCC, which I encourage everyone to do.
