I wouldn’t use PRINCO if you’re going to back up your DVD collection. As Surg said the disc may not be able to playback after a period of time. If you’re wanting to test out the discs because of your JVC standalone dvd player then use PRINCO DVD+RW or DVD-RW. Even Ritek is a better compatible brand to use than PRINCO. I bought some dvds from ebay and they were PRINCO discs. I ended up making back ups on all of them because I didn’t want to take a chance that the discs wouldn’t playback in a year’s time. In fact one of the movies wouldn’t read correctly, luckily I was able to use my other pc’s dvdrom to rip the movie. It’s the dye that PRINCO uses that is crappy so there is a higher failure rating after a period of time. In other words the longevity of the disc is very short.
You can get some good sales from Office Depot, Office Max, Best Buy and Compusa when they have the FUJI, VERBATIM AND MAXELL DVD MEDIA on sale. I usually get those buy one get one spindle free. Don’t waste your time with cheap media because in the end it may just bite you in the ass.
