DeVeDe is a pretty cool app for creating DVD videos ready for burning to disk, in Linux/Debian. You can create CDs too, if you want. The interface is clearly laid out, and simple to use.
Many default will work to build an .iso file ready to burn.
For such a simple application, its really powerful.
aptitude install devede

Dead easy to use.
