On a machine that can use either of the above, does one have an advantage over the other?

DVD+R's slightly better at error avoidance and correction and you're a little more likely to be able to burn dual-layer, doubling the data capacity. DVD-R has been around longer so is more likely to work when you try and play it back in an older device.

Other than that, they're pretty much the same.

Nope - price *maybe* I seem to recall that once upon a time there was a price difference.

But basically same speeds, same capacity.

I could get all technical about the difference between + and -, but I think that's beyond the scope of the question.

SoulKiss' answer pretty much sums it up. There's no real difference in the technology. About the only problem you're likely to run into is any other devices you want to stick the disc(s) into, what do they support?

from memory - wasn't it -r that was a panasonic only format and then all the other manufacturers used +R, i'm talking about DVD players only. in a similar way to the blu-ray / HD-DVD format.

all writers for PC's support both but i do believe that was the original thinking behind the differences between + and - It was definately something to do with a panasonic patent.

DVD-R was developed in 1997 by Panasonic, and yes, they held/hold the patent on it. However, most players supported it fairly early on.

DVD+R was developed later, 2002, and as touched on above, has better error correction capabilities (due largely to ADIP vs LPP).

That's without getting down to the nitty-gritty details of each specification.

I was trying to give an answer that was meaningful to the question :)

Yes of COURSE there is a difference (http://xgrape.net/2007/07/25/dvd-r-vs-dvdr/) :)

Are you quite sure about that?
