mkisofs UTF-8 character Unable to make a DVD

[creznedmick]

Greetings
I am trying to use mkisofs to make an iso image of a dvd video file

#mkisofs -dvd-video -udf -o DVD.iso DVD/

INFO: UTF-8 character encoding detected by locale settings.
Assuming UTF-8 encoded filenames on source filesystem,
use -input-charset to override.
mkisofs: Unable to make a DVD-Video image.


I tried
#mkisofs -dvd-video -input-charset default -udf -o DVD.iso DVD/

mkisofs: Unable to make a DVD-Video image.

I am at a loss

I don't know why you're using the udf flag, what does it do? I use mkisofs very frequently for making dvd video iso's, and this is what I do:

mkisofs -dvd-video -v -o foo.iso foo/

Try it, it has always worked for me. Of course replaying foo with the right names.

Thanks for the reply
I pasted and copied the command from a howto I read on the net. As you can see from below your cammand takes me past the stage where either I thought the error was or shows up where the real error appears. But the out put isn`t any help to me

Any ideas

Can you try playing it with Mplayer, Xine etc? If it can't play there might be a problem with DVD/.

One thing you can do-- k3b and I think other burning apps can burn your DVD/ as dvd-video without needing an iso. It's under something like project types in k3b.

Or from the commandline do this (I took it from the bible-- the gentoo wiki)

 growisofs -Z <device> -dvd-compat -V <volumelabel> dvd/

The device name is usually /dev/hdc or /dev/hdd, well you can quickly figure it out. Replace dvd/ with DVD/ and volume label is whatever you want to label it. So you might choose FOURFEATHERS in your case.

I really thought we had it there the burner fired up and was spinning like a top.... but then the error;

/dev/hdc: "Current Write Speed" is 6.6x1385KBps.
unable to WRITE@LBA=0h: Input/output error

do you know what this means?

[mahlerfan]

It could be from writing too fast. You can adjust the speed with a flag, don't recall but if you look at the man page it says it. I'd hate for you to end up making more coasters before you discover what it is though!

But really I think it's the same problem-- because it's still calling mkisofs isn't it? So it's not really burning on the fly, it's calling the same program that you did before.

Go ahead and try playing DVD/ with a player and see if that works. If DVD/ was corrupt that would explain the problem.

I have actually made a copy of this dvd using nero under windows so I know it is not the dvd. I have similar files I would like to burn and am using this one to try and get it rigth.
I have googled and found a post or two that reckon it is probably a speed issue, but no answers. So now I am reading the man page will let you know.
Thanks for all so far
Michael

[mahlerfan]

Oh dumb question if it is encrypted do you have libdvdcss installed?

Sorrow and disappointment
same error with "-speed=1" flag added. Note speed change from 6.6x to 6.1x

/dev/hdc: "Current Write Speed" is 6.1x1385KBps.
unable to WRITE@LBA=0h: Input/output error
write failed: Input/output error

from the man page
-speed=N
An option to control recording velocity. Most commonly you'll
use -speed=1 with "no-name" media, if default speed settings
messes up the media. Keep in mind that N essentially denotes
speed closest to N*1385KBps among those offered by unit for cur‐
rently mounted media. The list can be found in dvd+rw-mediainfo
output.

Time for breakfast and a break
I will be back
