libdvdcss is not for the old-style support. Libcss is, you can 
use libdvdcss with libdvdread but better use limpdvdkit2 as it 
includes both with some patches...

You can ignore this normally.

Yes, not the same.

You only need the old-style support for direct file playback. 
But afaik it works with the new methode too (I think you have to 
set the env. variable then). But who needs file decrypten 
anyway? The best way is to use libmpdvdkit2 and play the DVD 
normally with mplayer -dvd <title nr>. You don't need to mount 
the DVD in this case...
