I think i have ansewered this to other post, but Herrie will intoruce both Windows and DOS flashers, meaning you can make the NEC2500A v1.0X firmware to v1.07 DLBS


any ideas on when we can see this new firmware from herrie?

As soon as Herrie finishes its work, probably it will take a while to get good stuff

Ok I went from retail 2500A 1.6 to 1.7 and then to Dangerous brothers K0P2 and now its a 2510A and DL.....

How do I go to the Herrie DL firmware and what is better with this firmware?...Bitsetting, what does that mean in layman's languague :)

Can someone clarify this?

With the DOS flasher you can go to the new Herrie's firmware when its available, it has improved writing strategies for many media and booktype setting, meaning you can change the ID of the burned media from DVD+R DL to DVD-ROM DL for higher compatibility

Thanks guys for all ur help. One question though, with Herrie's new firmware, can I flash it in windows or will I have to do it in DOS?

p.s. I just got my nec yesterday and flashed it to 2k5107b9a and it works like a charm, using memorex dvd+r, burns at 8x the last 50% using dvd decrypter, very nice job!!!

When Herrie releases firmware, it will include a windows flasher so no problem, the DOS flasher is for people with NEC2500A OEM drives or have used other firmware (for example 2510A firmware...)

There are some choices:

a) The Official v1.07 firmware
b) Unofficial v1.07 with Herrie's magic at it
c) Unofficial v1.07 with Herrie's magic at it and Double Layer

I haven't personally tested any of the above firmware, except the last one and only with Double Layer media, maybe other members can help

Hi everyone, I'm new to register to this forum, but I've been a big fan for some time now!

First off, I just wanna thank emperor for your excellent trials for 2500A DL and Laffin_Assassin for the recommendations. I recently bought an ND-2500A from newegg.

I've got a question, though. Since I bought it from newegg.com, I think it's OEM hardware, does everything still apply (compatibility with KOP or Herrie's new FWs)? I chose to buy this drive because of it's potential as a DL burner. Also, is there any difference in how I flash my OEM drive compared to, say, a retail drive?

Hi Guys,

I'm also a Newbie . First of all, I want to thank you, too. Please keep the good work up! I'm a big fan of it!

Since, you are using LiteOn Drives to verify the DVD+R DLs, i wanted to contribute some lines of an article about DL which was published in the latest issue of the C't Magazine in Germany. They tested the new Philips DVDR885P and verified the outcome:

"Obwohl die DVD+R DL bei professionellen Messungen gut abschneidet, haben einige Laufwerke Schwierigkeiten, den zweiten Layer korrekt zu lesen. Dies betrifft nicht nur Laufwerke von LiteOn, sondern auch einzelne Modelle von phillips, BenQ, Pioneer und Xoro. So brach das DVD-ROM Laufwerk XJ-HD 166S von LiteOn kurz nach dem Layer-Wechsel den Lesevorgang ab. Der aktuelle DVD-Brenner SOHW-812S konnte den zweiten Layer zwar lesen, die Messsoftware "KProbe 2.1" zeigte aber auf dem zweiten Layer wesentlich höhere PI-und PO-Fehler als auf dem ersten an. An dem leicht erhöhten Jitter und dem hohen Asymmetrie-Wert der Disc dürfte es eigentlich nicht liegen, eher sind die Lesefehler auf Mängel in der Optik der Laufwerke zurückzuführen."

Translation:

"Although the DVD+R DL gets good grades in professional measurments, some drives have difficulties to read the second layer correct. This occurs not only in LiteOn Drives, but also in some drives from Phillips, BenQ, Pioneer and Xoro. The LiteOn XJ-HD 166S stopped reading shortly after the Layer-alteration. The latest DVD-Recorder[from LiteOn] SOHW-812S could read the second layer, but KProbe 2.1 showed considerably more PI- and PO-Errors than on the first [Layer]. The slighty risen Jitter and the high Asymmetry-Value of the Disc shouldn't cause the problem here, the read-errors are more likely caused by lacking drive optics."

Test Results:
DVD-Recorder: Phillips DVDR885P (T1.4)
Disc-Manufactor: MKM(Phllips, Verbatim) DVD+R DL, 2.4X
Manufactor ID: MKM 001 (Testsample)
.

PI Sum 8 / PIF / POF (Layer 0): 26 / 8 / 0
PI Sum 8 / PIF / POF (Layer 1): 42 / 6 / 0

DC-Jitter max / avg (Layer 0): 8.2% / 7.7%
DC-Jitter max / avg (Layer 1): 9.7% / 8.9%

Asym min / max. (Layer 0): 0.72%/5.91%
