dvd + r
We have to copy DVDs for work purposes and stupidly I have ordered DVD+R instead of DVD-R
Will this make any difference or will they work the same? I dont want to open the pack and try it in case i have to return them

One problem you may have is that the device you want to USE them on after you have created them may not support DVD plus.
I think most devices nowadays support both plus and minus, but some older devices may not support plus.
Assuming all the devices you are going to use to CREATE and USE the DVDs on are fairly new it should not matter too much.
I gather DVD plus is better for data backup, but not sure of the technical reasons why.

vhg ... 1/2 right ... some old PC drives will only read - or + (but this almost always only applied to CD drives ... hardly ever DVD drives)
DVD + is optimised for media
DVD - is optimised for data
The file allocation table and sector sizes are the key
a data file data can be large or small ... but must be accurate the emphasis is on error correction ... not necessarily on speed of access.
although because a CD/DVD is usually written all at once
fragmentation is not generally an issue
Media on the other hand ... tends to be large, digital .... and rely on a steady stream of data which can be relatively error tolerant - the signal is decoded as it is being extracted ...and as it is being played so there is a double error "trap"
most domestic dvd TV recorders/players work to + .... quite a lot can't cope with - so mp3 despite being technically data .. is best recorded to + discs
