I tried this with a small (1.6GB) dvd.  I used the command:

dd bs=2048 if=/dev/dvd of=name.iso

It always copies just a few bytes and then dies with an error:

dd: reading `/dev/dvd': Input/output error
384+0 records in
384+0 records out
786432 bytes transferred in 0.016091 seconds (48873878 bytes/sec)

Does the same with /dev/cdrom and /dev/hdc.  cdrom and dvd are links to 
hdc.  I even tried it in a root terminal but got the same thing, so I 
know that it's not a permissions thing.

The dvd is mounted and accessible from the desktop so I _should_ be able 
to dump it to an iso file.

Anyone know what's going on?
