[MPlayer-users] Error cracking CSS key

[Rodrigo da Silva Guerra]

Hello,

I am trying to be careful to not post unnecessarily already posted bugs. Even 
though, if someone read this and believe it was already posted somewhere else 
please let me know, and sorry for the inconvenience.

The problem I am about to describe bellow also seems to be happening with 
another players, as I posted already elsewhere: 
http://www.linuxquestions.org/questions/showthread.php?s=&threadid=291349

It seems MPlayer is not successfully able to crack the region code in my DVD 
player, and it appears to be playing uncracked data, and thus some audio and 
video outputs start to complain and nothing but noise comes into the screen 
and speakers.

My distribution is SuSE 9.2 downloaded through FTP, with kernel:
[CODE]
guerra at guerra-laptop:~>  uname -r
2.6.8-24.11-default
[/CODE]

I downloaded the MPlayer v1.0pre6a source and essential codecs package and 
fonts and skin, compiled, and installed it. But when I try to play DVD with 
MPlayer, I get this (this is long!):

This computer comes with a MATSHITAUJ-822Da, ATAPI CD/DVD-ROM R/RW drive which 
is /dev/hdc and SuSE's "Hardware Info" reports being with UltraDMA/33, using 
the driver PIIX_IDE (among other information).

The region setting is 2, as expected:
[CODE]
guerra-laptop:/home/guerra # regionset
regionset version 0.1 -- reads/sets region code on DVD drives
Current Region Code settings:
RPC Phase: II
type: SET
vendor resets available: 4
user controlled changes resets available: 4
drive plays discs from region(s): 2, mask=0xFD

Would you like to change the region setting of your drive? [y/n]:n
[/CODE]

Now I'm confused, because I searched for this and it is very strange that 
nobody else complains about something similar. If it were a bug in MPlayer, 
libdvdcss or in one of the players or their dependencies, or the 
distribution, for sure, someone else would have realized the same thing.

I'm affraid this is some different region protection in the hardware, as this 
is a new machine, but I am not so expert to assert this with 100% certain.

What should I do?
