I've not found Nero to be very good at dealing with DVDs. CDs it can't be beaten but they don't seem to have got it right as far as DVDs are concerned.
Regarding Pinnacle Easy DVD creator, again, I found it far from easy. It also take ages to render a disk.
Have a look at click here Get the free trial before you la out any cash and see how you like it. Although we've mainly gone on to Pro software now, we still use WindDVDCreator as it's so easy to use and quick with its rendering.
