Please help me with DVD image

[Jenda]

I have a little trouble making a video DVD image using dd. The man and "info coreutils dd" do not offer any help.
All I get is:

jenda@niniel:~$ dd if=/dev/dvd of=dvd.iso
dd: reading `/dev/dvd': Input/output error
1216+0 records in
1216+0 records out
622592 bytes transferred in 6.426452 seconds (96880 bytes/sec)

Can anyone please tell me what to do?

DVD movies are a little different animals. You will have to use something like dvdbackup. You can also shrink them to DVD5 using something like lxdvdrip. Also, dvdshrink works well under wine.

Thanks, Void Main. But to update the situation: It worked, and xine plays the movie noprob. Maybe cleaning the disk helped.

I figured it should work but I thought maybe they put some errors on the disk to prevent saving a backup but I'm not sure that any of the apps I mentioned handle that anyway. The apps would save the image in decrypted form though.

Yes, you're right, but I'll wait with all the DL-ing till I have broadband (i.e. like a week or two).
Thanks anyway.
