Single Layer / Dual Layer?

Sorry this is a stupid question.

Is there any way of telling if my blank DVD is Single Layer or Dual Layer? I no longer have the packaging, and the top is plain white.
Is it quite unlikely that it would be Dual Layer?
Thanks,

Matt

could always pop it into the drive and open up nero cd/dvd speed and have a look at disc info and see how many layers it says if you look the image says it all :slight_smile:


Or ImgBurn & take a look at the right hand window.
