DVD discs do nothing in FC6 Zod

[bioRX <shaun.grant1@xxxxxxxxxxxx>]

I pop in a Compact CD mounts lovely,
I pop in a DVD Disc (either data or movie), nothing, the CD Drive
dissapears in Computer (as in computer gnome) and thats that.

can anyone advise me on how to get this working? libdvdread is in and so
is libdvdcss. still nadda. 

there also isnt a /dev/dvdrom either, if that explains things.

thanks

ben
