[Lianna]

Hi
I have just bought a Pioneer DVR108 can anyone give me a quick and simple explanation about what the difference is between these 2 formats - and +???

Thanks

Basically, DVD+R's are generally more reliable for burning (newer style disc) whereas the DVD-R's are a bit less reliable for burning but supposedly compatible with a few more DVD players. :)

Thanks so much ;)

Found this on the net!

Difference between DVD-R and DVD+R

DVD-R:
- developed by Pioneer
- linear (sequential) data format (meaning: single, continuous stream)
- lacks random-access capability
- lacks native defects management
- relatively inexpensive

DVD+R:
- developed by the “DVD+RW Alliance” (Dell, HP, MCC/Verbatim, Philips, Ricoh Sony, Thomson, Yamaha)
- has many characteristics of DVD-R
- can be formatted as sequential data streams (video) or random-access (similar to DVD-RAM technology)
- compared to DVD-R, the DVD+R incorporates a higher frequency wobble in the embedded microscopic tracking groove
- "lossless linking technology" (the recorder can stop and start the writing process with extreme accuracy)
- good defect management ensures data read / write accuracy

So all in all, the DVD+R seems like the one to go for. :)

Except for the fact that more players seem to be compatible with -R .... all very confusing.

I'm told that +R also has the ability to be "multi-sessioned" (that is, have data written to the DVD at different times), while -R doesn't share that capability (that is, once you burn something onto it you can't add extra data in the future).

Making +R obviously a superior choice when it comes to use in data backup.

-R's multi-session fine on my PC's.
It's all very confusing, although I have heard before that +R is a better format...

DVD-R is an official DVD format, "+R" is not.
