Many people have questions about the differences between DVD formats and the compatibility of the discs in different players and recorders. Hopefully this can answer some of those inquiries.
The two are competing technologies that use different formats. No single company owns “DVD” and both technologies have their differences and advantages. DVD+R allows multiple layers for per disc while DVD-R only allows one layer. Multi layer DVD+R allows for more capacity than DVD-R, therefore it is more expensive. Also, DVD+R DL/+RW format offers more space for anyone who wants to record their own movies and audio and play in their own computer but not in a DVD or BD-r player.
DVD-R and -RW are officially approved by the standards group DVD Forum, which was founded by Mitsubishi, Sony, Hitachi, and Time Warner. DVD+R and +RW formats are not approved by the DVD Forum standards group, but instead the DVD+RW Alliance. The DVD+RW Alliance is supported by Sony, Yamaha, Philips, Dell, and JP. According to the DVD Alliance, using a DVD+R/+RW recorder will let you instantly eject without having to wait for finalized formatting. Also, it allows the ability to record one DVD partially on different recorders, such as a PC and then on a TV. It will let you simultaneously record on parts of a DVD that have been previously formatted, and allows for enhanced ability to edit file names on the disc. Lastly, it claims 100% compatibility with all other DVD players. We at http://www.cameratodvd.com/ are not finding that to be true. Older DVD players may have a problem playing them. We also find there are some players that like only the DVD+R.
When you transfer video or make video for others to view, here is the bottom line. You can use either DVD+R or DVD-R and make sure it has been finalized.
