Quality of Media???

[Graiskye]

Howdy, I have been having a lot of bum copies lately? I wonder if it is due to the quality of the CDR I have been using, or something else?! First thing I guess is the media? Does it make a difference? Sorry if this is a dumb question, but I got to start somewhere. Also if quality disks do make a difference what kind?? Thanks to any any all who rep, Graiskye ps. Shoot should have used search. K found bunch of threads on disk quality so I think thats taken cers of, but how would I go about determining if I have a bad recorder set up, or drive, I am using nero 6, with an Hitachi LG-GCC-4480B CD-RW/DVD-Rom disk, sorry 'bout the convoluted post(not using the search first).
