DVD Burning Issue

[Tricky]

I have just purchased some new DVD-R's from Scan £5.86 for 25
Same brand and make as I've had before Mirror Platinum 4x DVD-R

Only difference between these and my previous ones is that they are silver and the old ones were white.

Now the problems:
With my SONY DRU-500A (Flashed to x4) smaller files (ISO) approx 1.1gb write fine but larger files (ISO) at 2.9gb fail writing the lead out track. Home made DVD movies also failed on writing which is about 4.3gb. (Tried at x2 & x4) - Writing the either of the 2.9gb ISO or DVD to a DVD+RW, then doing a disk copy (via an image) also works fine!!!

Yet using my other machine which has a NEC ND2500 in the DVD wrote fine and therefore I assume the 2.9gb ISO image would.

The older media works fine in both drives with all the files...

I am running NERO 6.3.0.3 on the Sony (failing machine) with XP SP1
and
I am running NERO 6.3.1.25 on the NEC (working machine) with XP SP2

So what is the problem?
I could update my NERO software to the 6.3.1.25, but why does the old media work?

Maybe it's a bad batch of blanks?

edit - have you tried defragging your hdd in the dodgy one just to make sure it's at it's peak?

Same blanks work fine in other machine (unless it's every 2nd disc!) and also when doing a disk to disk copy via a image.

I'll try the defrag *cheers*

Now working:
Defragged all drives although XP said didn't need to
Upgraded firmware on DRU500A to 2.1a from 2.0g
Installed NERO 6.3.1.25 Upgrade

So I guess one of the above fixed it!
