pd, you cannot download packages from https://help.ubuntu.com/9.04/musicvideophotos/C/video-dvd.html page becuase of apt: prefix in the link. Only systems that using DEB package managers (such as Ubuntu, Debian and others) can be able to download and install such packages. You clicked on this link using Mac computer that does not support deb packages. If you want to just download packages without installing them, you can use http://packages.ubuntu.com page where you can search package database for Ubuntu. Although you should be aware that in this way you couldn't be able to install some packages because of dependencies.
I'm converting this bug report to a question, becuase it is not a bug in Ubuntu documentation. Feel free to continue to report any other bugs you may find. -- Unable to download the extras on the 'Playing DVDs' page https://bugs.launchpad.net/bugs/373988 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
