[twincling] Unable to recognise DVDs on Kubuntu 9.04

[Anirudh Ramachandran]

Hi

I have a DVD-RAM drive on which both CDs and DVDs were recognised by Windows
XP, Windows Vista as well as Ubuntu 8.04. But with Ubuntu 8.10 and Kubuntu
9.04 (which I am using at present), I am only able to recognise CDs. DVDs
are not being recognised at all, whether they be commercial xor DVD-Rs I
have burned in the past.

Please help me.
