The reason for this post is that I had a load of problems burning Video DVDs (DVD-R and DVD-RW) with Nero on my Pioneer 104. The discs seemed to burn OK but weren't playable on anything, not even the drive which wrote them. CD/R and CD/RW were fine, and data DVDs worked too. I was beginning to despair with the DVD-R/RW format for video and when I recently acquired a DVD+R/RW drive which wrote DVDs playable on anything I was convinced that DVD-R/RW wasn't a great format for video purposes. Then I remembered that it used to work, at least on PC drives, till I flashed it to 1.40 and around the same time upgraded Nero.
The DVD+RW drive came bundled with Nero, so I installed that version on the PC with the DVD-RW, using the serial provided. Lo and behold it worked with DVD-RW and they're readable on my standalone machines. The bottom line is that my downloaded 5.5.10.x made DVD coasters, the bundled version didn't, the downloaded version didn't when I used a number I picked from the May 2003 TSRh keygen.
There had to be an explanation for this, and I've spent a happy evening pulling the Nero code apart. The answer is simple; Ahead have built routines into the later versions of the software which prevent proper operation if the serial isn't valid. Unlike earlier versions which barfed at an invalid serial, Nero accepts mathematically plausible serials but apparently misbehaves silently if it doesn't like them. There are two nested calls which invoke a bunch of subroutines which I can't be bothered to trace, but the validation is much more complex in 5.5.x.x than it used to be. This means that older keygens might appear to work but your media will be at risk!
