Can't read a DVD!

Hi all,

I run with a Mac so the multitude of PC software ables to break a protection don’t help me.

My system is OSX Panther. Some DVD don’t mount, i mean that when I insert the DVD, it spins unusualy then it is ejected, as with a protected cd audio.

Example: I was easily playing “road to perdition” last week, but today it is ejected from the drive!! Perhaps I made an update from apple that check for anticopy protections?

WHAT CAN I DO ??!! :(((((
PLEASE HELP !! :bow:
