I don't believe this article is any longer valid Guttsy Gibbon is just to old think it should be archived also has nothing to do with security so don't know why it appears in this menu structure - Delboy
A problem occurred the other day when a DVD video project (Video TS) burned with K3b was unreadable within Windows. When inserted on a windows machine, it would show as a blank DVD, yet on my Ubuntu desktop it showed the Audio TS and Video TS folders and played with no problems what so ever. Several forum posts later it was discovered to be a know bug in Hardy Heron with the precompiled version of geniso included in the distribution. The cure is to downgrade to the gutsy version of it. This was not as straight forward as clicking on the deb file, as the package manager would just tell you it already has a newer version installed. So this is how it has to be done.
Download genisoimage deb package for gutsy onto your harddisk from Genisoimage. Next use dpkg in a terminal to force the install by going into the directory where you have downloaded the deb file and typing sudo dpkg --force-downgrade -i genisoimage_1.1.6-1ubuntu3_i386.deb input your password and the file will be downgraded.
Next open up synaptic package manager from the system/administration menu, and search for geniso, highlight it by selecting it then click on the package menu and select lock version. This will stop the update manager trying to revert back to the buggy version.
Any Video DVD's burnt with K3b should now be readable other OS's.
Thank to all the people on Ubuntu forums for the anwers, especially bedege for the very clear instructions.
