i just came here to post a similar question, and before i made a new topic i saw this one.
I also have a dell, but i got mine in march with a 8X DVD+RW burner (or it tells me on the printouts) i've used 4X DVD's since then. Today i just got 200 BenQ 8X DVD+R but it still burns at 4X and i use nero with the write speed at maxium. any idea where i can find out what speed my burner really is? or is nero detecting it wrong?
well i check device manager and looked at my burners website http://www.teac.com/DSPD/support/dt_dvdr_drives/ide_dvdr.htm
which says my burner is a 8X
my burner is a teac DVW58E (8x DVD+R / +RW)
