Just getting used to my RD-XS34. So far I've only used the discs I already had: Philips 8X (FUJIFILM03) and Samsung PLEOMAX 8x (OPTODISCR008). Errors with 4 out of 6 Samsung discs (I'll definitely have to avoid those...), one Philips disc written correctly and one failed because of a HDD reading error. Can anyone suggest brands that work flawlessly with this machine? Here's some I would like to try: - Memorex 8X (CMC MAG AE1 or RITEKG05); - Datawrite RITEK-Optima-Blue 8x (RITEKG05); - Datawrite Titanium 8X (CMC MAG. AE1); - Datawrite Yellow 8X (CMC MAG. AE1); - Ritek 8x Printable Inkjet (RITEKG05).
