TSGL: DVD burner

[Computerfee]

Hi there everybody!

I have been trying like mad to get a DVD burnt last week. Tried Windows XP's
burning facility and my Nero 8 Essentials and started to wonder why there
was no point given to choose burning a DVD. In the end then I thought the
drive might be no DVD-burner after all, though I thought the fact that it
was a CD-burner and DVD player for sure, would mean, they would not produce
something strange like that, so checked the box it came with several years
ago and yes, it definitely is a DVD burner: Pioneer DVD-RW DVR-105.

But it seems the device has forgotten it is meant to burn DVD's, it does
read all the DVD's I have here (which are not that many different ones) as
well as all CD's and it does burn CD's. I checked online and found it to be
known for problems but all the people mentioned problems with burning no
CD's at all and not mentioned the DVD-part at all. By the way, it is the
first time I ever wanted to burn a DVD with it, so I don't know, if it ever
was able to do it.

I really would like to know, whether it is possible that the power supply
problem I had before (without recognizing it for a rather long time) did
somehow affect/damage only the DVD-burning part of the drive? Or can the
laser that burns DVD's be the problem when it does burn CD's all correct? Or 
can a DVD that it does not recognize, make the possibilities of burning 
DVD's not show up at all? I went and got a single sided DVD-RW 1x-4x but it 
might be too new/good or the "wrong" make then after all?

By the way, a firmware update of the drive was available and I have
installed that, so should all be installed correctly, as I learnt no drivers
are necessary for such a drive.

Have a nice day
