I get this message right at the end when I click on the ¨Generate DVD structure¨ icon. This message appears when the application is busy doing the ¨Finalization of the project¨.

The log is as follow:

I am using MANDVD v2.5-4 on Kubuntu 9.04

[Patrick Penzler (serdanikufesin)]

I had the same problem on Ubuntu 9.04. It seems to come from the line

dd if=/dev/zero bs=4 count=1920 | lame -b 128 -s 48 /dev/stdin silent.mpa

in the script menu.sh. Apparently, newer versions of lame need the switch -r to accept raw data
(i.e. without header). Thus,

dd if=/dev/zero bs=4 count=1920 | lame -b 128 -s 48 -r /dev/stdin silent.mpa

or better

dd if=/dev/zero bs=4 count=1920 | lame -b 128 -s 48 -r - silent.mpa

works.
As a workaround, execute the above command in the destination directory before clicking
on the "Generate DVD structure" icon.

[Marius Groenewald (groenem)]

Do I need to run the command everytime I want to ¨Generate DVD structure¨? Or can I only Edit and Save one of the application´s files?

[Alessio Treglia (quadrispro)]

This bug has been fixed by 2.5-5 release available for karmic

[JC Hulce (soaringsky)]

Thank you for taking the time to report this bug. This issue has been fixed in newer versions of Ubuntu, and Jaunty is EOL, so I am closing this bug task.
