Double/Dual Layer DVD media is much more complicated to manufacture than Single Layer media, and the only brand that generally get it right is Verbatim.
RITEK G05 is very problematic media - a lot of it degrade very fast, before or after burning. You might be experiencing the difference between good and bad (or new and old) RITEK G05 media.
In any case, I'd suggest you find some other media than your AOne DL media and your RITEK G05 SL media.
I have no personal experience with your particular DVD burner.
