In my country USA their the same price (mostly). I would have thought due to the dual wars that would have helped to lower prices and intoduce faster speeds. Just like the HD-DVD BluRay wars now they're both rushing to bring out players first.

maybe that's why there's more crap DVD- out there than crap DVD+

dolphinius_rex wrote:DVD+R is harder to make
The production of masters for the DVD-formats is somewhat more complicated due to the requirement for the pre-pits that are located on the land areas between the grooves. For these formats the groove has a fixed wobble frequency without modulation and the addressing and timing control is provided by the pre-pits.
The production of masters for the CD and DVD+ formats is relatively straightforward with only a single, wobbled laser beam being required to produce the groove.
Although traditional master recorders used for these formats are dual beam recorders, only one beam is actually switched on during the recording.
The more complicated DVD- formats, with pre-pits have, up to now, also been produced using a highly complex dual beam recorder. In this type of recorder, one beam is used to write the groove while the second beam produces the pre-pits. As optical discs are specified in terms of the readout signals obtained and not by the geometrical structures, the use of a dual beam recorder is only a method and is not a pre-requisite.

I don't think so. If anything it is (was) the other way around:The production of masters for the DVD-formats is somewhat more complicated due to the requirement for the pre-pits that are located on the land areas between the grooves.

There now exists single beam method for DVD-R too but every DVD-R still needs to be pre-recorded with CSS copy protection though.
I also very much doubt your 10x more sold/made DVD-R numbers. In fact if I remember correct it was a study not that long ago showing DVD+R selling more in retail stores like Bestbuy.

Während eine DVD+R nach diesem Schritt bereits fertig ist und nur noch mit einem Label bedruckt wird, muss auf eine DVD-R noch der CSS-Kopierschutzring gebrannt werden.
Dieser soll verhindern, dass man von geschützten Video-DVDs 1:1-Kopien anfertigen kann, ohne den CSS-Kopierschutz knacken zu müssen.
Babelfish translation:
While a DVD+R is already finished after this step and only with a label one prints on, still the CSS copy protection ring must be burned on a DVD-R. This is to prevent that one can make from protected video DVDs 1:1 copy, without having to crack the CSS copy protection.
DVD-R is more compatible with DVD players then DVD+R, even with bitsetting.
Bitsetting simply gets around a firmware bug in many old DVD players.

Amen to that.

New crap DVD+R is coming out though... now that people are getting better at dodging Philips
