Personnally I use Nero Burning Rom 22.214.171.124, Alcohol 120% or IMGBurn (Depending on what I need it for).
Also here is a list of the discs that I currently have:
Datawrite Titanium 16x DVD-R (MCC 03RG20)
Ritek 8x DVD-R (Ritek G05)
Panasonic 8x DVD-R (Taiyo Yuden TYG02)
Bulkpaq 8x DVD+R (PRODISC-R03-003)
Verbatim 6x DVD-RW (MKM 01RW6X01)
Maxell 2x DVD-RW (MCC 01RW11n9)
You might find that DVD+R perform better on this drive, but I use DVD-R because I consider them to be more compatible with most standalone DVD Players.
If you have the same discs as me, maybe try writing at a slower speed like 12x or 8x, or try different software like "IMGBurn" or "Alcohol 120%".
Otherwise if you want disc suggestions maybe look here at the following posts which should be a lot more helpful.
NEC ND-4570A : Post your scans and questions here
NEC ND-4571A : Post your scans and questions here (Basically same drive)
TBH, I not that satisfied with the NEC ND-4570A. I only bought the drive on impulse. I was actually queing up to equire about an ASRock Motherboard (which they didn't have) and I overheard the person at the counter serving the person in front of me mention "NEC 4570A". When I got served, I ask whether they had this drive and thought it might be about time to replace my "NEC ND-2510A 2.05C" (Liggy/Dee Modified firmware , then give this to a friend of mine), and maybe it will be better at the Ritek Discs than my "BenQ DW1640 BSOB" (RPC1 TDB Firmware ).
I only managed to use the Drive a few times in the week it was working. But I managed to burn a few discs that had a terrible scan in "Nero CD-DVD Speed 4.11". (Maybe it's just me )
Personnally I hope that a new firmware will be released by NEC or whoever to improve the writing of this drive, especially on DVD-R.
Hope this helps
