Here is the situation. I have a Memorex Dual Layer DVD CD recorder player sim although a bit older than the following:
Just the other day bought some Memorex -R +16 DVDs, and after about two years of service it would not recognize the DVD says it is an incompatible format. I put in some DVDs I had sitting around (Memorex +R +16) and they worked fine, then tired some -R +8 and they worked fine as well. Went out bought some Sony DVD -R +16 and got the same incompatibility error. What the heck is going on. Both the so called "non compatible DVDs are +1 to +16 writable" and my burner is -R +R dual layer compatible. Both my computer and nero burning software cant read these new dvds.
