I’m having serious issues with my NEC 2500, in particular in burning of DVD+R media. I recently bought it as a 2100, then upgraded it to a 2500 under DOS, using the Dangerous Brothers’ nec2x00a.exe with the 21002500.BIN. I then updated it using Herrie’s 1.07v2b5 firmware. For reference, my main drive I’ve been using until now with great success is a NEC 1300, mostly used with Herrie’s 1.09b. With the 2500 I’ve actually had great luck with burning DVD-R media, I’ve tried a few cheapo Sonic discs, MUST001 and AN31, and they even burned better than my reliable 1300 with these discs, all burned at 4x. HOWEVER! I’ve now burned 10+ Ritek branded RICOHJPN R01 and ~5 Ritek R03 DVD+R discs, as well as one TDK branded RICOHJPN R01 disc, and every one of the burns has been horrible!!! The discs are typically riddled with read errors. The drive is setup as Ultra DMA mode 2 under the control panel in XP. P4 2.8, 512mb RAM, I’m burning all of my discs from ISO images on a Seagate 200gb HD (not the OS HD) set to Ultra DMA mode 5. I almost always burn with DVD Decrypter, although I tried one disc with the latest version of Nero, with the same terrible results. These same DVD+R discs I’ve had NO trouble at all burning on my 1300, but they are terrible on the 2500. I’m testing my discs using CD Speed’s Disc Quality Test with a LiteOn 163. I tried reflashing 1.07v2b5, same bad results. I just now flashed to 1.07v2b4, same bad results. What in the Hell is going on here?!? It seems to be burning DVD-R media great, but it is horrible with DVD+Rs… I’ve burned all but a couple of the DVD+R discs at 4x, I tried a couple at 6x and they were even worse… I don’t care about burning past 8x, I don’t mind burning at 4x but I’d like to be able to burn at 6x or 8x on occasion. I’m desperately looking for any suggestions, as I’m about to throw this POS out the window and go back to my 1300 or buy a 3500.
Here’s some screen caps, hopefully they show:

this is a 6x burn:
These are some of the BETTER burns I’ve gotten so far with the 2500 using DVD+R media - most of the others were even worse.
Here’s one of my cheap Sonic MUST001 burns with the 2500, this is a pretty solid burn for this media, this test looks essentially identical to most of my burns of the same media on my 1300:
And here are typical burns of the same DVD+R Ritek R03 and RICOHJPN R01 media burned on my old NEC 1300:
