I brought a spindle of Verbatim and Sony DVD-R and they worked wonderfully. I have tried literally 10 other brands since and none of them work. Meaning after I am prompted to insert media and I put in a blank the program goes 'oh no' and kicks out the dvd and tells me to insert a blank one. I went and bought 2 spindles of Sony and now those two do not work anymore either. What can i do? my computer burns to those DVD's just not when I use Clone DVD. is there a brand of DVD that always works? Please help!!!
