some questions about libdvdcss...

[fv]

hi everyone,

I made some tests with some dvds I have here and libdvdcss-1.2.3 and libdvdcss-1.2.4

I really surprised by the results.
Maybe someone would like to explain why libdvdcss cannot access to some sector on the disc ???
I thought fisrt that my dvd-drive was fuck up.
But the error doesn't the same if I change the dvd or the version of libdvdcss.

Basicly, that means I cannot read scrambled dvd... on my dvd-drive. But I used to with old vlc...

Here are the results of my basic test.

1) dvd : snatch zone 2
