Was able to buy the Linuxtag 2003 DVD from Lehmanns- Berlin. At first sight : nice piece of work!

However was not able to use the DVD just as a Knoppic CD. The DVD boots and everything is normal till the opening screen (in KDE) with ao all the info about the DVD. After a few seconds the screen freezes : keyboard and mouse do't react. The only thing to do is to reset or to shut down. Same problem under Fluxbox : after a few seconds (trying to load Kshisen) I had to shutdown.

Should I blame the DVD-disk or my DVD/CDROM drive?

Thanks beforehand for any help.

Regards,

Georges.
