Comment 4 for bug 843930

> What was the last version that worked for you? Does downgrading fix it?

2:1.0~rc4.dfsg1-1ubuntu3 seems to be the latest working version.
Downgrading fails on dependencies:

mantonyan@merelin:~$ sudo dpkg -i /home/mantonyan/Dropbox/mplayer_1.0~rc4.dfsg1-1ubuntu3_amd64.deb
dpkg: warning: downgrading mplayer from 2:1.0~rc4.dfsg1+svn33713-1 to 2:1.0~rc4.dfsg1-1ubuntu3.

I suppose that the issue appeared after the following update:

mplayer 2:1.0~rc4.dfsg1-1ubuntu3 -> 2:1.0~rc4.dfsg1+svn33713-1
libbluray0 -> libbluray-bdj and libbluray1
