DVD-R ? DVD+R ??

[Brody8877]

What is the difference in DVD-R ? and DVD+R? I hav a DVD+RW drive what is the difference between a DVD-RW??

Nothing anymore. Old DVD players are more likely to play "-" but any player from the last 2+ years plays both.

If you really care, try Advanced Search > archived threads, for the last few times this was asked.

You should also note that many of the new stand-alone DVD recorders only like one format or the other for recording. So far the A/V manufacturers haven't gone the full compatibility route for recording.

- is kinda inferior, but not in a way most will notice. think cdfreaks has an aritcle on it. +r for data with multiple sessions, wastes a lot less between but price difference makes - generally ok.

Also, just something you might want to notice if you're looking at DVD burners, some burners like samsung and sony have different write speeds for DVD-R and DVD+R. For example: The sony DRU-710A is a 16x DVD writer but it writes DVD+R at 16x and only writes at 8x for DVD-R.

How do you use Google? No difference. They are both round and plastic as far as you are concerned. Go for name brands of either media and you will be fine. Search for media code compatablility for your drive to see which ones are best and rated the fastest.

I have an old Pioneer DVL-909 laserdisc/DVD player from around 1999 or so and was suprised that it played DVD-R, DVD-RW, DVD+R and DVD+RW without any problems! I do prefer DVD+ though, mostly because the media produced today is faster than DVD-. Most manufacturers seem to lean toward DVD+ as we see with dual layer burners only being for the + side (for now). Plus, I believe, you can add more data to a DVD+R but once you burn to a DVD-R thats it. I could be wrong tho so no one yell at me!

Why is DVD-R "inferior?" I read once that Ritek DVD-R are the most compatable for DVD video players. So I've always used Ritek DVD-R for videos. I've also burned some data onto a DVD-R and it was easily ready by a computer DVD-ROM drive.

What exactly would happen if I burned data onto an "inferior" disc? Quality control on the part of the DVD manufacturers should be high. You should be able to burn data or video onto either a plus or a minus, without ever having to worry about it. Right?

Are we there yet?

For now, the only dual-layer discs are plus. So, that might be the eventual winner of minus vs. plus

I think I read somewhere that the +R have addressing data for the sectors hard-coded (hard-sectored), whereas for -R it's in the pre-groove, but it has to be burned by the burner again in order to be read by players (soft-sectored). Not sure how true that is, can anyone confirm? Plus, -R has slightly more capacity than +R, either due to that former factor or something to do with the area reserved off of the disc for key-block storage.

Real-world differences between the two are slim, other than +R is starting to get 16X-speed media, and good-quality (T-Y) +R 8x will burn at 16X in some drives. I think that the format-wars are stupid myself, and while most PC burners don't matter format-wise for data recording and retreval, there are still some players that matter.

Also, I have an older 2X Creative IDE DVD-ROM, that won't read -R or +R at all. It reads pressed discs (dual-layer too), along with CDs, CD-Rs, and CD-RWs, but I haven't been able to get it to take recordable DVDs at all. It can detect *something* is present in the drive, but not what it is. I think that indicates that the reflectivity is within range, but it seems that the firmware locks out all but DVD-ROM booktype or something. It's an ancient drive anyways, but it's RPC-1/region-free by default, and nice and quiet during playback. I would like to be able to use it to play my recorded DVDs just for viewing purposes, might stick it and a video card with hardware-assisted DVD-playback into another older PC to make a DVD-player-only box, would be nice if I could work that out. Anyone know about hacking older DVD/CD-ROM firmware that uses an OTI 910/911 (?) chipset?
