[quote name='x_fiddle']The Benq 1620 drive is about the same price and is just as good a burner if not better in some areas.
*Official bitsetting support
*Better at burning over media speed rating. (i.e. 4x media at 8x)
*Disc media troubleshooting
I would only get the 3500a if you mostly burn DVD-R/-RW media however.[/quote]
All this can be also done with the 3500A as I do it myself. Many utilities exist to change the bit setting on the fly. My NEC3500A burns 8x on 4x media (ridata) and 12x on 8x media (also ridata). If you use low quality media, you will get low quality results, as is the case with any DVD burner, not just the NEC. I burn DVD+R media without a hitch.
As far as software goes, you guys should look at DVDShrink and DVD Decrypter. Both are free and work well.
