Managed copy wouldn't be any good unless the disc shipped with versions of the movie for different players or could transcode them on the fly *and* had the appropriate USB functionality to actually transfer said copies to the devices, *and* had the means to manage devices which presumably would have to be registered to a user in some manner.
What would help the situation enormously is if portable devices adopted a single profile & level of AVC/AAC for audio/video and a single DRM for management. That way it doesn't matter what device you have, just that it supports some common platform and away you go - buy content or use managed copy from anywhere to anything.
It's no wonder managed copy got stuck on the backburner.
