DVD+RW or DVD-RW media for standalone DVD recorder (NEC ND-3550A)

[qanda]This thread is about the NEC ND-3550A. Click here to see full specs[/qanda]I have a standalone DVD recorder in which the drive recently stop working. I replaced it with my NEC 3550 from my PC, and stranglely enough it works!!! :slight_smile:

I use the DVD recorder only with RW media, and when I want I transfer the content in the PC for the editing stuff. Recently I found out that most of the RW media I use are burned with bad quality. Maybe this happens because of the very low speed used in the DVD recorder. If I got it right, HQ-1hr is about 1x, SP-2hrs = 0.5x and so on. I use good brand media such as Verbatim DVD+RW, TDK DVD+RW, TDK DVD-RW etc, all of them rated up to 4x (I try to avoid higher speed rated discs)…

Do you have any suggestions on the media I can try to have good quality burns in such slow recording speeds?

Thank you!!

Unless the quality is so bad that it cannot be read, it doesn’t matter. All RW burns look like crap anyhow. So as long as the PC drive can read it, it’s all good.

Thank you! :slight_smile: Yes the PC can read them (with only one exception but I guess it is the particular disc).

But sometimes the standalone DVD recorder cannot read them!!!

Then I do the following: I rip the RW to my HDD, and I burn the same disc in my PC at 4x. Then it plays fine in the standalone as well :wink: But it is inconvenient… This is the reason why I assume that it has something to do with the very low recording speed.

The NEC 3550 was working fine in my PC, both as a reader and as a writer…

Well, stick with the Verbatim as long as it has MCC media codes, there is none better.

The Verbatim DVD+RW discs I have are all “MKM A02 000 (00h)” according to CDSpeed… Maybe I should try buying in another shop to get some with MCC codes! I thought MCC were only the DVD-R discs…
Thanks again for the info!

MKM for Dual Layer and Rewritable media.
MCC for single layer media. Plus or Minus.

Thank you for making it clear to me :slight_smile:

Below you can find some scans to get a better picture of what I mean.

The first two are recorded in the standalone DVD recorder, using the NEC 3550, the first at HQ-1h (1x), and the second at SP-2hrs (0.5x).

The third one is when burning the same disc at my PC, at 4x. It looks that it is not a defective disc!




@yyy

Just curious, what brand & model is your standalone?

It is a Contel DVR 200 made in China :slight_smile:
It has very good picture though, but its drive was not so good from the beggining. Now I have its drive replaced with a NEC 3550 from my PC, just to see how it goes :wink:

Allow me to correct myself. All the discs that came to my hands follow this rule. Recently I found this isn’t true. That’s what a NEC firmware will tell you -> http://club.cdfreaks.com/f86/optiarc-ad-7200a-s-ad-7201a-s-ad-7203a-s-results-discussion-233536/index49.html#post2235522

DVD+RDL -> always MKM
DVD+R -> always MCC
DVD+RW -> Can be MCC or MKM
DVD-RDL -> Can be MCC or MKM
DVD-R -> Always MCC
DVD-RW -> Can be MCC or MKM

As you can see, at the time I am writing, single layer Verbatim write once media will have MCC codes on it, always.

Thanks for the clarification. Since I’m interested only for RW in this case, should I care if they are MCC or MKM coded? Is there any difference in the disc quality?

Can’t be sure about that.
What we know, and if you follow the link from my previous post, you will observe the following. MCC A01 is 2.4X rated DVD+RW media. MKM A02 and MKM A03 are 4X and 8X DVD+RW media respectivelly.
For DVD-RW media MCC was used for 4X and below media. While MKM 01RW6X01 is 6X rated media. So the only difference is the speed you will be able to write the media at.

As for the quality of the burns. It will depend on both the burner and the media.

Regards.

They will be written at a maximum of 1x speed!

Where I live, I can find Verbatims:
DVD-RW 4x - they should be MCC
DVD-RW 6x - they should be MKM
DVD+RW 4x - they should be MKM

Since I have already tried the MKM +RW 4x, I’ll get some MCC -RWs to see…

I appreciate your help!!

Hi.

Writing these discs at 1X speed will probably be not so good. Can’t you write them at 2X or 4X?

No, because the drive is in a standalone DVD recorder, so all recordings are in real time!! This means max 1x at HQ mode, where about 65 minutes fit in a single layer DVD disc.

This is the reason why at first I asked the question. To find RW media performing good at VERY low writing speeds!!!

Thanks again :slight_smile:

Well, then seems to be a good idea, to opt for the lowest speed rated media.

Because the NEC 3550 drive does not have firmware support for 1x burning, I suspect that it is in fact writing at 4x and suffering continuous buffer under-runs. This will account for poor quality burns. The surprising thing is that you’re getting readable discs out of it at all. The drive will automatically set speed at 4x when any of these discs are inserted, and this cannot be changed. Been a while since I had a 3550, it might possibly have support for 2x on some -R media, but it’s doubtful.

I think so too :iagree:

I loaded the latest fw for 3550 to Media Code Speed Edit. In the following text you can see the writing strategies for RW media. For +RW it seems that the lowest available speed is 2.4x, and for -RW it is 1x!!! Maybe if I can find these 1x media, the NEC will write them at 1x, and the results will be better! I hope… :slight_smile:

And probably I could swap a strategy from a 1x media to the media I have… I think I have to disassemble the standalone again and “patch” the NEC fw again :slight_smile: :slight_smile: :slight_smile:

What do you think???

That was really helpful!! Thanks a lot :clap:

The NEC firmware is designed to accept speed commands from burning software. Hard to say what, if any, speed commands are being sent by the player’s electronics. My assumption is that the player used a drive with special firmware that only burns at 1x. PC drives seem to all default to the highest burn speed, not the lowest.

But like I said initially, if the disc is readable in the PC, it doesn’t matter how good the burn quality is. Stick with 4x -RW and you should be good.

You won’t find any 1x RW media. But you might find some 2x rated RW on a store shelf somewhere (probably Memorex). IF it has no speed rating, then it’s “1x-2x”. Apart from the Verbatim -RW listed in the code, there isn’t any that I would bother trying.

These 3 are the lowest rated (4x) Verbatim DVD-RW media I can get:

  2. http://www.multirama.gr/products/product?pid=0247271&catid=080300
  3. http://www.e-shop.gr/show_ana.phtml?id=ANA.VER00552

Probably all of them are the same MID :slight_smile:
I’ll get some to check…

Do you think that the NEC is “suffering” from putting it in the DVD recorder? Up to now it seems to work without any problem. Is there any chance to break it???

Thank you all for your help!!!
