[MPlayer-users] mplayer and Windows Media DRM

[Andrew Pimlott]

This is a beginner question, but I can't find any clear answer anywhere.
I downloaded a Windows Media Video 9 file from movielink.com, which uses
some kind of Digital Restrictions Management.  Is there any way to make
mplayer play it?  If not, could mplayer pop up a message saying it can't
play it (and why), instead of displaying garbage?

Here's what I did:  I installed mplayer, using the mplayer-586 and
w32codecs Debian packages from ftp://ftp.nerim.net/debian-marillat/.  It
plays non-protected wmv files.  When I tried playing the DRM-ed movie, I
got the messages at the end.  Also, using strace, it appears that
/usr/lib/win32/wmv9dmod.dll was loaded.  The video window did not at all
resemble the actual video contents, but it wasn't static--there were
slighly coherent blotches of color moving around.  There was no sound.

The file is within its playable period.  I can open it directly with
Windows Media Player (ie, not using MovieLink's software) with no
problems.

Again, my question is very basic:  Is this the expected situation?  If
we can already use the video codecs from Windows, what else from Windows
is necessary for DRM?  Any hope for improvement in the near future?
Thanks for your help.
