You can only use the DVD format that is supported by your hardware. DVD+R and DVD-R are different and competing standards for recording on DVDs. The difference between DVD-R and DVD+R is not important for DVD players because virtually all players play both formats; the difference is important in DVD recorders.
edit Origin and industry support
The DVD-R standard was developed by Pioneer. It is used primarily by Apple and Pioneer. In addition, this format is supported by the DVD Forum, but is in no way an industry standard. The DVD+R format is supported by Philips, Dell, Sony, HP, and Microsoft.
edit Cost comparison
DVD-R discs are usually cheaper than the DVD+R format.
edit Differences in Features
DVD-R/RW discs can only be written to in one layer on the disc's surface. On the other hand, DVD+R/RW discs can be written to in multiple layers, giving them slightly better and more disc storage than the DVD-R format.
edit Advantages of DVD+R
According to the claims of the DVD Alliance, using a DVD+R (or DVD+RW) recorder will provide the following advantages over a DVD-R recorder:
- Instantly eject without having to wait for finalized formatting.
- Ability to record one DVD disc partially on PC and partially on television.
- Background formatting: while the disc is being formatted, you can simultaneously record on already-formatted portions of the same disc.
- Enhanced ability to edit filenames, movie and song titles, and playlists.
- 100% compatibility with all other DVD players, while still enjoying these extra recording features.
