Please help me with DVD image

(1/2) > >>

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:

--- Quote from: niniel ---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)
--- End quote ---
Can anyone please tell me what to do?

KernelPanic:
What do you intend to do with the image?

Jenda:
mount+play, or burn later.
But it seems to be working now. Is it possible that watching the movie first could help? Like it being loaded partially into memory or sth. Or perhaps just wiping the disk, as I did?

Kintaro:
Err, read the dd manpage.

You are getting an error on the disc, a scratch or something like that.

dd if=/dev/dvd of=dvd.iso conv=noerror

will ignore errors.

worker201:
Check out alternatives, like makeisofs and growisofs, which may behave better.
