I'not css expert, but shouldn't the drive itself decode the file in case
of encryption? Or maybe windows players store these keys somewhere?

Hmm... I suppose everything I have uses MLP. The patch is nice, now at
least mplayer tries to play audio only instead of showing video with
random noise, but even format is incorrect: for different .aob files on
the same disc, it displays
AUDIO: 44100 Hz, 4 ch, 24 bit (0x70000000), ratio: 529200->529200
(4233,6 kbit)
AUDIO: 48000 Hz, 1 ch, 24 bit (0x70000000), ratio: 144000->144000
(1152,0 kbit)
AUDIO: 48000 Hz, 6 ch, 24 bit (0x70000000), ratio: 720000->864000
(5760,0 kbit)
I'm not sure, but I guess the real parameters are 24/96/6 or 24/96/2.
Only very loud noise is heard.

OK, I'll upload something soon.
