Some DVDs work. I haven't figured out why some fail.

It loads:
eben@pc:~$ grep udf /proc/filesystems
eben@pc:~$ sudo modprobe udf
[sudo] password for eben:
eben@pc:~$ grep udf /proc/filesystems
udf
When I try this:
eben@pc:~$ sudo mount /dev/hda /mnt/temp -o ro -t udf,iso9660
mount: wrong fs type, bad option, bad superblock on /dev/hda,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
This shows up in various logfiles:

OK, all NULLs. Should I conclude that it's having a physical problem
