i no verbatim is the best,but it also is the dearest.which is a decent make to use.cheapist.i have some back ups arround 2 years old ,which have started to form bubbles on the surface,and now wont play.
don,t spend your money on cheap dvd,s.
on the end you will pay the same price for the cheap one. because game wont play anymore (need to backup again).. and your x-box laser don,t like the cheap dvd,s.
save your money and x-box :D... Buy Verbatim Dvd,s
here is the deal, cheap DVD's use cheap dye and cheap material.
That causes them to have less of a lifespan and also problem like the one your having.
So in the end you do not save money, you just waste it because now you have to buy more DVD's to do your games. Just get quality DVD's to start with. Verbatim for instance i beleive has a 10 yeah dye life.
