I've been using DVD-Rs for years now and initially stuck with Sony products since all my equipment was Sony as well. This lasted until last year when i got three 100 pack spindles at different times and places that were horribly defective. The drop-out rate was at least 60% unuseable. Too bad, because they had the nicest surfaces for labeling. I switched to the Verbatim brand, seeing as not many places carry Maxell, which was my recording brand of choice from the cassette days. Memorex is the most commonly found but their quality reputation as been abyssmal since at least the '90's. In any case, I had good luck with the 100 pack spindles of Verbatim DVD-R until recently when i ran into a bad single batch. I figured I'd try the AZO (red dye) version which runs about 30% more on cost, but it seems like they will be phasing out the original type soon judging by the drop in price for that stock. My first order of DVD-R AZOs came in as DVD+R AZOs, maybe due to substitution, and I quickly found out what I was missing. The DVD+R picture and sound quality is approximately the same, but the load and finalization times are about 70% faster. They seem to play well even after some scuffing and wiping. Over the whole spindle, I had only 3 duds. At current prices, that translates into 90 cents of waste, a pretty good deal all around. Since almost every player after 2003 supports the format I see no reason not to use these excellent discs that are a desireable combination of quality and affordability.
