I tested this with both an isobuster generated ISO from an exising physical DVD and an NRG file generated with Nero using the image recorder.

NeroLIB.dll for C# created using tlbimp, ildasm, ilasm of NeroCOM. Burns CD's just fine. NeroCMD burns both DVD images just fine. BurnImage code is as follows:

ndrives = (NEROLib.NeroDrivesClass)neroclass.GetDrives(NEROLib.NERO_MEDIA_TYPE.NERO_MEDIA_DVD_ANY);
ndrive.BurnImage2(f,NEROLib.NERO_BURN_FLAGS.NERO_BURN_FLAG_WRITE,0,NEROLib.NERO_MEDIA_TYPE .NERO_MEDIA_DVD_ANY);

I have posted about a burning problem before where it would fail when starting the burn with "Recorder function not implemented" after updating to 6.6.0.3 this issue was resolved though now I cannot fixate. I can go through Nero Express afterwards and fixate and read the data just fine.

Thoughts? Comments? Bugfixes from Ahead Software?

Does it happen every time the same way? Have you tried different burn speeds?

Yes, this happens every time with NeroCOM. I have tested this on 2 computers, 3 different drives and 2 media formats (and 2 different brands of +R). I have tried different speed settings as well.

I guess when all else fails, fix your own problem. DVD burning with NeroCOM and C# seems to produce a fixation error in new versions unless you include the following burn flag: NEROLib.NERO_BURN_FLAGS.NERO_BURN_FLAG_DAO

Once I set this burn flag, life was good.

It could be that virtual memory at your computer is close to max. I had same problem and I adjusted my Virtual memory and wala....it is burning as before. here is the link which will lead you to increase or adjust your virtual memory....happy burning.
