On the page I mentioned before I found another patch, claiming to be 
'nicer', which works in slightly different way. I didn't test it on the 
problem DVDs yet (but will tonight), but at least normal DVD play is 
still possible. I've created a suitable patch for libdvdnav's dvdread 
(as before). This is merely looking into which one works better, no 
final solution yet (unfortunately).
