Mplayer, however, does not support those instructions and runs right into the bad sectors.

The dvdnav-Patch is able to play this sort of discs, at least at my 
batch of problem discs. It seems to use some altogether different read 
mechanism to steer around the sectors. So ATM I can finally play all my 
DVDs again (subtitle problem(s) solved, Copy Protection playback solved)

Unfortunately, when I play a title with DVDNAV it shortly plays some 
other title in the playback lineup (usually a bit from the company 
logo), and dumping the track does also not work on all titles, since it 
dumps over and over the dvd menu.

TO make things short: I'd need a playback of dvd://x with the playback 
capabilities of dvdnav://x, but please no menus. :)
