Hi....complete newby here!

I need help and although the 'problem' I have my have an obvious answer, I'm stumped.

I recently installed an ASUS DVD Rewriter Model: DRW-2014L1 which shows as a DVD-RAM Drive on My Computer.

So far I've been able to record DVD-R & RW discs but not DVD+R & RW ones.

When I insert a +R/RW one, it's just not recognised, it only recognises & works with -R/RW ones.

I read the specs for the ASUS and it appears it should work with either - or + types.

What am I doing wrong?

I would welcome your advice please,

Many thanks,

Tony
