Verify the disc basically means Nero will check to make sure the contents on the newly burned disc match the original file/disc. I've never used it, and I never ran into any problems.
If you have never had any problems without it then what?s the point in Nero having it as an option?
I have been burning DVD's fine without it but tried it yesterday and 2 films past and one DVD came up as 'Verify failed' right at the end of the disc. But I watched that DVD last night and it works fine so I don?t understand why it failed.

For mission critical backups I'm sure this might be a good option. Anyway, Nero is loaded with many options that most won't ever use.
When you burn a disc, there can be recoverable errors that do not match the original disc. The keyword here is recoverable error, which is not noticed during playback. Nero's verify disc option does a bit by bit comparison and is looking for an exact match to the original disc.
For a more detailed inspection of my burned discs, I use Nero CD/DVD Speed and perform a disc quality check. Since I have a BenQ burner, I can also use QSuite. There's a link below for the latest version of CD/DVD Speed, which surprisingly was updated today.
If your burn contained an unrecoverable error, chances are Nero would have simply aborted the burn and reported the fatal error; resulting in a Coaster.
dvdnoobie you seem to know a lot and I am grateful for your advice. Could you also please explain what the Nero Burning Rom option 'Determine Maximum Speed' is used for and why I would need to use it. Thanks
You will find that most members here burn their DVD's at half the rated disc speed and do not enable the maximum safe burn speed option in Nero.
Your DVD burner has firmware, which is basically on board memory storage. This firmware contains the write strategies for supported media. Normally a default write strategy is used for unknown media. Since firmware and support for media can vary, it may be useful to determine the maximum safe burning speed.
The quality of blank media can vary too. I've seen warped discs out of the spindle, scratched discs from shipping (no spacer ring in DVD spindles), and dye variations. All of these issues can result in a failed burn, but some may be overcome by burning at a slower speed.
Of course if you are burning on the fly, determining your maximum safe burn speed is important. In such cases you want to make sure your burner is receiving data faster then it is writing that data. But for DVD's, burning on the fly is something I would never recommend.
