Not going to notice any differences.
The way I describe it is,
"Think of a gramophone record with the groves and bumps. -R writes and reads to the groves, whereas +R writes and reads to the bumps"

Now THAT, is the simplicity I love.

All I know is, that most of what I've come into contact with, prefers DVD-R discs. That's what my PC cupboard is stacked with, and never had a problem. Have had problems with DVD+R though.

Go for DVD-RW, their not much dearer and you can re-use them.

Works out expensive if not required for reuse though!

Some people say that DVD-R is more compatible, and some old drives might not read DVD+R.
However, I always and will always buy DVD+R because:
1 - I think the format is superior
2 - My burner (and many others) allow bitsetting, i.e. burn the DVD+R leading track so that it effectively become a DVD-ROM, making it very highly compatible.
So if your burner supports bitsetting, I'd definitely use DVD+Rs.
I never use RWs because they wear out much quicker than advertised and are much less compatible.

It just occurred to me, that OP seemed to think that, because he has a dual layer capable drive, he has to use dual layer discs.
NOT SO! You will normally use single layer disc, unless otherwise needed. (Home made video's etc)

Also, the question wasn't really answered effectively.
A dual layer disc can hold twice as much data as a single layer disc, and that's why it is the common form for commercial video's (films etc)
Having a dual layer drive, means it can play films etc, which a single layer drive can't.

Now that's nonsense. When a computer DVD drive is labelled as 'dual layer' it means it can WRITE to dual layers. Even older DVD drives that are not 'dual-layer' can still read dual layer DVDs such as films.

Suppose I started earlier than you, before that were true.
