ASUS DVD-RW 0804P firmware

The last time when I’ve changed my writer’s firmware was ~ 2 years ago.
Now I’ve some problems with some media that I write… Verbatim, Traxdata…
They are burned corectly but Nero doesn’t write the lead-out.
With Memorex it’s all good.
I know my problem sound a bit general but tell if what I’ve got now is good enought (and new) so that I shouldn’t have problems now.
I’ve got:

DVRFlash 2.1 and DRW-0804P_FW121 (from asus.com).

You won’t need DVRFlash for this!

Update creepy Nero, then try again.
