Well part of the issue is that the BitSetting (as I understand it) has never been properly resolved - sure, you could use a modified 2500 firmware, but as I said, if I’d wanted a 2500, I would have bought a 2500.
Now I just wish I’d known the 3500 was coming out so soon - I’d’ve waited on buying the unit. But at the time, everyone was so hyped up on the 2510.
I guess I’ve been rather fortunate in that the only program I ever have any burning problems with is Nero (and that’s definitely a problem with the program as other have reported it as well - when Nero just stops burning and hangs). I’ve been using DeepBurner for most of my burning, and it’s been flawless.
I have yet to burn any dual layer or DVDRW discs, but the DVD-R discs have been fine. I also have a stand-alone DVD player that is DivX compatible and plays most anything, so I haven’t yet encountered the booktype problem.
