I used EasyBoot (it is not free) and I menage to make booteble DVD with both Windows XP /SP2 and Knoppix 3.9 (because leatest version 4 is on DVD). Since I had too much space left I put some programs also. It was pretty big job but after couple weeeks i did it. Notice: 1. Virtual machines SHOWS the results (I used Microsoft VM) 2. You can not make DVD ove 4GB because installation of Win XP won't work. 3. You may have various problems with the menu picture but you have nice forum here: http://forum.ezbsystems.net/cgi-bin/ikonboard.cgi?act=SF&f=1
