for them who may not know the tream DL it not for Download for DVD it means Double Layer
Stander DVD-R or DVD-RW holds 4.5GB avg
Double Layer "DVD-R DL" holds about 8.4GB Avg
as i know there is no DVD-RW Double layer 8.5GB at all, i did try to find it but nope don't think no one make a DVD-RW DL at all.
there are two type of DVD Burners out there one is stander DVD Burners that only do 4.5GB dvd's and there are the DVD Double layer DVD burners. they all so burn CD/minnie CD/ pocket CD and RW types.
