mount a dvd burned in linux, permission rights?

[flowin]

I have a dvd burned in Linux, that has permissions rights to the administrator.
i have to enter a password to copy the file in Finder.

I get this error in VLC.
access_file: cannot open file /Volumes/movies/0000.avi (Permission denied)
access_file: cannot open file /Volumes/movies/0000.avi (Permission denied)
main: no suitable access module for `/Volumes/movies/0000.avi'
macosx: Error: Unable to open '/Volumes/movies/0000.avi'


how do i get rid of this error ? mount it manually(how.. mount_udf ...?)?
any easy solution to this?

i do get this error for normal dvd video disks as well
