Nero write error

Well i’m backing up my first ever DVD, using the great How to Do by Chicken Man How to backup your DVD to DVD±R. I’m burning with Nero version and I get to about 70 percent complete and it clunks out on me. Tells me I had a write error.

What do you guys make of this?

Well, after hours of searching for other problems and answers to remedy the situation… I decided to take out the ‘coaster’. Well, it seems that the DVD has not one (which I removed) but TWO protective covers on it. I"m assuming that it weighed it down too much and caused it to spin too slowly???

Tried it again and it’s a go!
