DVD-R and +R drives

[butterfm]

Hi,

Maybe a daft question but can DVD+R drives read DVD-R disks.
Obviously they can only write +R but can they read all formats.

hmm, I'd like to know this as well...

what about the other way round? i.e. DVD-R drives reading DVD+R written discs?

The answer to both is YES.

It's the writing process that's not cross-compatible, but both types of drives can read finished DVD's regardless of their format. When I say finished, I mean having at least one session that is closed.

Thanks cdogg. I thought that may be the case but wanted confirmation.

Why are there two different types in the first place? What's the difference?

Hi there,

'Why are there different types of VIDEO formats? Why are there different TV standards?' ... because those who invented them think that theirs is the better!

All DVD Burners (for PC) today can read the diff standards, only a few can burn both standards aswell as DVD-RAM... ie. LG Electronics GSA-4082B burning (DVD -/+R 8X/8X; DVD -/+RW -RAM 4x,4x,3; CD-R 24x; CD-RW 16x) reading (DVD-ROM/-RAM 12x/2x; CD-ROM 32x)... a truly nice drive...

I think my NEC 1300A burns both types

Electronic companies basically developing differant technologies at the same time.

VHS
Betamax
SVHS
Hi8
8
VHSC
Phillips 2000
etc etc

The video market being a prime example of multiple formats being championed by differant companies all at the same time.
Alot of this is down to patents, companies don't want to pay to use others technology so they develope a slightly differant system that they hop will become the "common" standard.

Start by questioning and soon you will be answering.
So please take but remember to return and give when you can.

To make things more confusing (just thought of this) if you have a panasonic dvd recorder (as in home) they record in DVD-RAM a format only played on certain dvd players
However they make up for this with the use of timeslip
Anyway just another wonderful thing in the world of so called industry standards

Dragon,
As others have mentioned, a lot of it has to do with a company or group of companies putting forth the effort to create a new "industry standard". It's all about owning the patent my friend!

The formats differ in the way the DVD is written to. Even though they are created differently, the finished product is supposed to appear the same to PC DVD-ROM players. Set-top home DVD players are another story and are more sensitive to the format and type of media used. Although either format is more than 90% compatible, companies have long since been releasing dual-format burners to make up for the missing 5-10%.

You are correct so far. But unfortunately the story is not all told. Many DVD burner manufacturers specify certain brands of media to be used in their machines, if you do not use them the burner slows down or writes with errors. They don't tell you which media is approved but it is build into the firmware. The first thing I always do is hack into the firmware and remove the restrictions, at the same time I usually remove the region codes so that the drives can read all regions and remove the burn speed limits. With the latest Pioneer I just copied a DVD movie at a speed of 12 times normal, this is on Konco 4 speed blank media. The verification was ok, no errors. However for data burns I use a max. speed of 8. Also the dual layer DVD blanks still come in two different formats which are not compatible which each other. DVD RAM is another issue. The blanks can be rewritten more then 100000 times, again they use a differnt format optimised for max access, reliability and speed. This means that DVD rams are incompatible with many DVD readers. So thats enough for now (2 am). Regards

Jurgen

I'm aware of the region code issue but have not heard of the media brand restriction. Where can I find more info or better yet how do I find a fix for this?

Cheers
