[SLE] Philips DVDRW228 : kernel: I/O error

Hello,

I've been reading faq's, downloading tools, compiling ... but it still 
doesn't work :-( .

This is the problem : I'm trying to mount a DVD so I can copy the vob 
files on my portable which does not have a dvd-rom drive. When I mount 
it, autofs uses the udf filesystem. All files are readable except the 
main movie files. They produce an I/O error. Strangly enough, mplayer 
can play the dvd normally ( I reinstalled mplayer with css decryption 
support ). I tried to dd the disk directly to my portable, but this 
breaks the movie ( garbeled image and bad sound ). Once the kernel has 
had an io error, the drive stays blocked ( even the files I could read 
are now unreadable ), until I open en close the tray.

I upgraded to suse 8.2 and upgraded the firmware of my drive to 1.51 to 
be sure. I tried with several disks, even with really old ones ( to 
check if there was a copy protection of some sort on there ). Since 
mplayer can play the disk , I suspect there's something wrong in the udf 
fs, since mplayer uses its own udf driver ( quote the mplayer homepage ).

Does anybody know of anything I could try ?

Thanks in advance !

Peter.
