None in terms of quality but DVD-R are best because they're cheaper and more compatible in stand alone players. The +R's were formulated by Sony & Phillips to corner the market - and their profits!

The -r format is generally a 'burn once only' format.
The +r format is excellent if you are into editing, as due to the makeup of the disc, you can edit/cut certain areas out, ie if you have a dvd compiled from the TV with adverts - then you can remove these AND still maintain the original content with subtible editing software.

also:
+R = VBR [variable bitrate]
-R = CBR [constant bitrate]

Got a Sony DRX500ULX that does a fine job of copying my original DVD's on +RW and +R ,but blows the session on both -RW and -R DVD's. I know the burner is okay, as I"ve been able to do full erasure on the -RW and use it as a data cd, but never to record movies. Any guess's why? I'm talking to the pc via usb2 and have not tried the firewier connection. Thanks

I should imagine that if your using the external version of Sony DRU500 that a firewire connection might help massively.

Ill just run through with you what the difference is between DVD-R and DVD+R
There is a DVD Forum consisting of 219 of the largest manufacturers of DVD Writing materials. It was decided in a democratic decision that the DVD Forum would go with the DVD-R rather than Sony and Philips +R system. Sony & Philips, though, 'hell...we're the biggest and best...screw you guys' and so launched they're own format.
In principle there is very .
little difference between the two types
Baabaa - the +R isnt generally a Burn once format, quite the opposite. As Herbsman says, the main difference is the bitrates on each. With a Variable bit rate, some say a better picture quality can be maintained. This is the main argument for +R.
However, the -R format, with its constant rate, is backed up by the DVD Forum and so will be compatible with a lot more home DVD players. If you were to go for a +R DVD writer, you may find incompatibility issues.
However, BLue Ray, a blue laser system will be released next year allowing up to 12 times the amount of data on one disk. This is due to blue laser beams being up to 12 times thinner than they're current red counterparts.
All in all... it doesnt much matter what format you choose, try a drive with both +/-RW, like the Pioneer A06/106 released on June 30th, as blue ray is likely to take over it!

While there may be very little difference between +R and -R. There are these other disturbing things. Like -R being about half the price. Like on identical machines (both pc's and burner types ((whether internal or external)) +R and +RW burn times and success are faster than both internal and USB...but don't try -R or -RW on the USB. It's real touchy! The firewire (external in this case) does as well as the internal drive in burning. On -R's typical behavior has the drive light doing apulse on pulse off routine, rather than the constant on burn light behavior of + disc's. Not to mention that vendors are starting to cluster around each other and recommending only certain vendor disk varieties and only certain revision levels for certification. What bilge! I went to a local Best Buy to look at burners and can you imagine my surprise to see what kind of blank is contained in the box?!? It was an RW type and what a shock (not) to see 4 out of 5 drives with a...you guessed it a +. Hmmm...vhs or betamax...+ or -???

Oriphus, point me to the part in my post where I stated that the +r was a 'burn once format' as I am having trouble locating it.
I suggest you read a little 'closer'.
Can you rewrite the ifo tables on a -r/-rw if you want to edit it?
I think you have to re-process the whole disc to another disc don't you (or am I mistaken?)
Personally I think +r shall become more popular, I have yet to see a -r standalone recorder (to replace the vcr).
It is rumoured that Microsoft are to back the +r format - which I believe is more to do with editing capabilities than just data burning....
In terms of compatibility issues, I have a dvd880 +r standalone recorder and I have yet to encounter an UNPLAYABLE +r in any standalone (-r) produced in the 880 recorder, inc a PS2.
Could be the software used that causes these problems - not using common standards...

Where USB fails, FireWire succeeds on the "-" burns. Now all I have to do is take this to all the standalone's that give "disk error" messages with good + burns and see if they will play my successful "-" burn...without chapter looping.

Guys - DVD-R and DVD+R have nothing to do with VBR or CBR. They're all blank discs and you can put whatever data you want on them. All DVD Video discs you buy or rent are VBR, since that is how the best picture quality is attained. If you make backup copies of discs, no matter which format you use (DVD-R or DVD+R) the resulting disc will be VBR (Don't believe me? Check the bitrate meter on your player).
You can also encode your own movies as MPEG-2, using VBR settings, using TMPGEnc or various other authoring packages. You can then burn these VBR files to DVD-R or DVD+R.
MikeBUK got it right when he said that the +R's were a marketing deal. Sony and Philips didn't want to pay the royalties to make DVD-R drives, so they created their own format. They're both generally compatible with stand-alone players, but I understand that there are a few machines that play DVD-R and not DVD+R. This is usually a reflectivity issue, and has nothing to do with the actual data on the discs.

xgadlp! I agree whole hardedly. But then there's the theory and practice, no! I can't really explain why disks like Imation +/- will play one my standalone, but on my daughters, only the -R will and not the Imation..but rather something that CompUSA sells. And, yes, hers is at least 2 years old. Suffice to say with all I've burned of late Name Brand media of moderate price (and as it pertains to XCopy) has no guarantee of success.
I would appreciate your explaining your middle paragraph a little more...like how exactly do I dupe, say my Predator, using the software you describe. It sounds as if a greater level of success might come from manual intervention rather thatn total software intervention (i.e. Xcopy!

Yeah, i think we all know that including herbsman, just that he was smoking some killer weed that night.
Here is all the information you will need on the differences between DVD-R and DVD+R:

An article: Why DVD+R(W) is superior to DVD-R(W) - http://www.cdfreaks.com/article/113/
Borrowed from the page:
- Better ECC
- Better power calibration info
- Better linking
- Less space lost in multiple writes (= sessions)

Excellent website analysis on the two formats. A bit over the head of most people, myself included probably. Im going to re-write it and post it in newbie terms. I suppose i should ask the site first if thats ok.
Thanks
Chris
