One's - and one's + ... I know!

Wife's trying to create a slide show presentation in Media Centre on her laptop that has XP.

Apparently you slot a -R DVD in the drive and it starts up some Wizard which take you through the process ... but only on a DVD-R ... or so it says.

She went to get some DVDs from PC World rolleyes (before she knew the -R requirement) and the guy said either -R or + R would suffice.

And the Wizard doesn't automatically launch upon insertion of the disk. SO does she really NEED some -R disks are are we doing it wrong?

Any help appreciated ...

Goin gback a few years, when DVD recorders first came out, there were two formats. Those recorders woul dnormally only allow use of either '-' or '+' discs.

As time has moved on, most devices are happy to accept both. However, this isnt always the case - my DVD unit in the car wont read DVD-R.

They have different kinds of error correction - it's a very geeky technical difference.

If the drive supports both, then either is fine, although I think -R is the "better" format for putting films etc on.

Whilst their is no appreciable difference between the two formats these days, the problem could well be with Windows. The DVD/CD Burning engines built in to XP are rather primitive (oneshot burning, no RW support, etc)... so it could be that the chunk of code that triggers the wizard isn't capable of handling +R's (or -R's as the case maybe).

Your best bet would be to return them and get them swapped. It might be worth getting a copy of Sonic or Nero Burning ROM, both of these can, i believe, upgrade/replace the internal engine.

I use sonic and can burn + / - discs, never noticed any difference.
