NEC 2510A writes DVD-R 4.0X only at 2.0X, a Rookie's problem

Hi there,

Unfortunately I’ve never been good at writing précis, therefore I apologize for the longevity of this post and ask for patience.
I’ve very recently purchased a NEC ND-2510A, which was supplied with firmware 2.15. Right out of the box, I flashed it with the official 2.16 firmware. I burned 4 movies onto Princo DVD-R at 4x using either Alcohol 12% ver.1.9.2 (Build 1705), DVDDecryptor 3.5.1.0 or Nero 6.3.1.20 with following Media code/Manufacturer ID: PRINCO

No coaster, perfect compatibility with either my Liteon XJ-HD165H PC DVD-ROM player or my standalone DVD players Toshiba SD-2550 and Panasonic RV-31 both 2-3 years old, low budget players. Only when I tried to make an Image of those copies with the 2510A using DVDDecryptor, some returned I/O error while DVDDecryptor was initializing the disc (while parsing IFO files ), still perfect image with the Liteon. This issue is only a nuisance and by no mean comprises the result, I wonder if this is what some refer to 2510A being a poor reader.

After that I bought some other chip DVD-R, which were just a bit more expensive than those Princo’s, they are all 4X DVD-R, but my 2510A only writes at 2X using any of the aforementioned softwares.

I’ve tried DVDinfopro and DVDidentifier to see if there was a problem with the DVD’s, and the result is as follows (you might as well skip this section!):

I burned two of these one With Nero and the other with Alcohol 120%, both at maximum available speed which was 2.0X, the one burned with Nero, although burned completely, had read problems with all my devices, in other words a faulty burn. With Pioneer DVR-A07 XLA at 4.0X, the results are perfect.

:a Could Read again :wink: All DVD’s as reported by DVDidentifier MODE SENSE Write Speed Descriptor, are capable of being recorded at 4X CLV/Non-Pure CAV – including the fact that a Pioneer A07XLA with original Firmware burned them all at 4X with perfect compatibility despite very poor outcome with Princo-, but their GET Performance Write Speed Descriptor or Available Write Descriptor with my 2510A are CLV 2.0X.

I concluded that this might be drive or firmware-related rather than a faulty recorder. But I would very much like your opinion. Is there any other way to bypass this issue?

I guessed maybe a hacked firmware would solve this issue, and after a quick inquiry, I found out that there are 3 hacked firmwares available on the net. One by Dangerous Brothers, which supposedly does not alter the writing strategies and only sets the drive to RPC1 and removes the riplock which currently are of no use to me, and the other two provided by Herrie 1.07 v.2 Beta5 and Herrie 2.16 (2510216 either dos or windows), which unfortunately due to Herrie’s site being down, I couldn’t download.

[i]Could someone please send me a link to download those other firmwares by Herrie, preferably the DOs version and the 2510216 file, or upload them.
Also your opinion about which of those would be the better choice is highly appreciated.

Thanx,

to the best of my knowledge none of the firmwares make any changes to the read capabilities except to allow ripping of dvd video at higher speeds. so if it is having problems reading they will most likely continue

Dear cnlson,

As I`ve mentioned before, the reading problem is just annoying, the burned Princo’s are in perfect condition.

The reason I intend to flash my 2510A with hacked firware, is to be able to write those other 4.0X DVD-R’s at 4.0X instead of the drive only being capable of writing them at 2.0X, in case this would be the solution.

Also I’m still looking for those Herrie - 10.7 v.2 beta 5 and Herrie 2.16 Dos ver., any idea where I might get them?

nevertheless thanx for your reply.

Any other opinion
