Commercial Answer The truth is that the two competing technologies use different formats. No single company "owns" DVD and both technologies have their "champions". DVD-R/RW was developed by Pioneer. Based on CD-RW technology, it uses a similar pitch of the helix, mark length of the 'burn' for data, and rotation control. DVD-R/RW is supported by the DVD Forum, an industry-wide group of hardware and software developers, and computer peripheral manufacturers. The DVD-R format has been standardized in ECMA-279 by the Forum, but this is a private standard, not an 'industry' ISO standard like the CD-R/RW Red Book or Orange Book standard. DVD+R/RW is also based on CD-RW technology. DVD+R/RW is supported by Sony, Philips, HP, Dell, Ricoh, Yamaha, and others, and has recently been endorsed by Microsoft. DVD+R/RW is not supported by the DVD Forum, but the Forum has no power to set industry standards, so it becomes a market-driven issue. Technical Answer DVD+R is a dvd disc that allows multiple layers for one disc where as dvd-r only allows one layer. They will not compete to become the de Facto standard, because they are both here to stay. Multi layer DVD+R can allow extra capacity per disc than DVD-R hence its high cost!

This page says it will use plus r keep in mind.. dvd+R maybe wont work on many of the older pc's dvd players. Here is a link that might be useful: http://support.gateway.com/s/notebook/2009/gateway/nv/NV73/NV73sp2.shtml

Ok...I just copied what it said I needed from the instructions. The installation from my old Dell was all on one disk. I'd be afraid I'd mess up the installation if it ended up on multiple CDs. Maybe I should say that there would be more chance for error on my part. The instructions also said that the USB key should have a minimum capacity of 8 GB. Well, when I go to Control Panel, I see there are 45 programs now with total space of 1.12 GB. So what gives with them saying I need a minimum of 8GB? I'm guessing that it would all go on one of the disks at the link below. About them...it says, "This recordable DVD features AccuCORE technology which is 100x more scratch resistant than standard discs. Fights static, repels stains and fingerprints" Here is a link that might be useful: 25 DVD+RW Re-Recordable DVD 4.7GB

This thread brings up a problem which I have ran into, so please forgive me if it looks like I am hi-jacking this thread, as that is not my intent. I bought a dvd/vhs recorder/player around Thanksgiving and used it to transfer home vhs video tapes to dvd+rw discs. The discs will play on my pc using various video programs. All went well until I tried to transfer the disc contents to my pc hard drive so that I could edit them. My pc has a 2 gig processor, 512 megs of ram, Win xp home with sp2 and a 160 gig HD with plenty of unused space. I downloaded a program called dvd shrink 3.2 hoping it would allow me to transfer the disc to HD. It was a no go as I keep getting various error messages. Does anyone know how to transfer files from a dvd disc to a pc hard drive? I'm baffled. Thanks in sdvance for any help.
