I have an NEC ND-1100A drive (DVD+R/RW) that I bought for under $200. I bought a stack of 100 Ritek 2.4x DVD+Rs for about $1.30 per disc, which seemed very reasonable to me. I remember when CD-Rs were over a dollar a disc, too, and at the time I thought that was worth it for copying^H^H^H^H^H^H^Hbacking up music and games.
I've copied^H^H^H^H^H^Hbacked up 35 DVDs since I got the drive. I have a Pioneer set-top player that I'd guess is 4 years old anyway, and a Playstation 2, and both play the movies without a hitch. I've brought them to a friend's place and they played in his player as well, though I didn't note the model. I'm not sure where the impression comes from that DVD+Rs don't work in anything and nobody uses them. I didn't read the article, but before I bought my drive I did what research I could, and there was a site I found that listed hundreds of set top players and the vast majority of them played DVD+Rs fine... if there was any problem, it was with +RW, but -RW wasn't exactly universal either. And why would anybody want to burn DVD movies onto DVD+RW/DVD-RW anyway? Do you burn movies, watch them, delete them, and then record onto the DVD again as if it were a VHS tape? I mean, you're already saving $19-some dollars if you're swiping a buddy's copy to make the disc, why not pony up the extra dollar and change and have copies of all of them? (This is a hypothetical question, as everyone on Slashdot knows that nobody abuses fair use rights.)
I've used my burner for legitimate reasons too. I have ~75gb of legal mp3s that I made from my own cds (I immediately rip and encode every cd I buy and then put the cd in one of my cd books at home. A couple years ago when I was getting ready to come to college, I didn't want to risk someone walking into my dorm room and walking out with 600+ cds just by lifting my three cd books, so I didn't bring them with me) and that I don't share on Kazaa or anything similar, and I would be forced to commit suicide if I were to boot to an unrecoverable fsck error, or my drive were to set fire (did I mention I have four IBM drives? I am a master hardware buyer), or any number of other things were to happen and I was caught without backups.
And as appealing as burning 110+ cds sounds... no thanks. Though I must admit, I anxiously await the day where blank DVD+R/DVD-R (whichever format wins out, I don't care) discs can be had for $.30 a piece in retail stores.
