I'd advise editing your post and removing the lines with your serial No. (the one that starts 1A20).

The write error could simply be bad media. Recompile the DVD again, but set Recode to write to a Hard Disk folder. Then burn the contents of that folder to a disk using the main Nero program. I see the media is reported as CMC MAG, that's notorious for producing coasters, and I suspect the problem is simply a faulty DVD-R.
