DVD Burning Problem

[lukx]

this is how it is.It's normal you can't burn whole 4.7GB it's like with hard disk.

[Pretorian]

Ok, but, just curiosity, why you can burn a 700 MB CD-R with really 700 MB data? That's why I thought you can burn the 4.7 GB from a DVD-R. :)



Thanks

I also would like to know answer to this question, this is strange.

[vinteg]

I know that you can only burn 4.37GB on a single sided DVD.

I tried to record/burn a blank 4.7 DVD-R using Nero 6 and it has written only 4.5 Gb, or, it has only made 4.5 Gb of the disc available. Is this a Nero setup (my) mistake, a media problem or a DVD drive problem, even it says it records dual-layer discs?

Thanks

Is the burning failing at the end or does it just not let you burn the disc?

From memory, DVD-R discs dont have 4.7gigs of space, its closer to 4.35

Did you try "overburning" the disc? Some drives have that option, never used it though so I can't comment on its effectiveness.

[Pretorian]

Vinteg: well, it's burning 4.5 GB in fact. But, as far as I know, I burned it normally, without any special option.

Imashination: no, it's burning "normally" (if 4.5 GB burning is the normal), my question was why it doesn't burn the whole 4.7 GB space, that the disc says it has, and burn "only" 4.5 GB. Like I said before, if a CD-R has 700 MB and you can burn the whole 700 MB, why you can't do the same with a DVD-R by burning the whole 4.7 GB from the disc?

SkyZero: no, I didn't. I have never used that kind of option as I don't feel too confortable with it (is it trustable?).



Thanks

That's weird. I'm never able to get past 4.4GB. Sometimes I use Toast and try to go past 4.3GB. It'll say the DVD is not full and I'll think it'll work, but the DVD never burns correctly for me. Heres a quote from my DVD Studio Pro3 Manual as to why:

What Do You Mean a 4.7 GB DVD Won’t Hold 4.7 Gigabytes?
With computers, memory and disk size are commonly expressed in terms such as kilobyte, megabyte, and gigabyte. Technically, a kilobyte should represent 1000 bytes, but due to the binary numbering system computers use, a kilobyte actually represents 1024 bytes. Similarly, a megabyte represents 1,048,576 bytes (and not 1,000,000 bytes) and a gigabyte represents 1,073,741,824 bytes (and not 1,000,000,000 bytes). Unfortunately, with DVD discs the terms megabyte and gigabyte do not use the same binarybased standard; they literally refer to the technically accurate 1,000,000 bytes for a megabyte and 1,000,000,000 bytes for a gigabyte. This means that a 4.7 GB DVD disc will actually hold only 4.37 binary-based gigabytes. While the difference is not large (relatively speaking), it must be accounted for if you intend to come close to filling the disc.
These links say the same thing:

Normally I know it can't burn past 4.37GB. Let me know if you're successful. Also, is this a Data DVD or are you authoring a DVD-Video disk?

That exert from your DVD Studio Pro3 manual is very confusing (at least to me). First of all, I take issue with it saying "technically" a killobyte should be 1,000 bytes. The metric system would interpret "kilo" as 1,000 but obviously computers do not use the metric system.

So if 1 KB is actually 1,024 bytes, and the label on the box is a rounded number, 1024 is larger than 1000 so why is the actual storage smaller than what's printed on the box?

Whenever I setup a project I usually leave room for the TOC. Buring ISO images gets a lot better, I *think* the TOC is in the image. I've burnt ISO images on CDR that comes really close to 700 MB, so I'm wondering if there's any benefits to making a 4.5+ GB ISO image first then burn the image to DVDR.

[vinteg]

Those links might make it a little less confusing for you. They explain the same thing, just a little more understandable. The concept itself is confusing and dare I say trickery?

Why they are marketed as 4.7GB when they only hold 4.37GB? Its the same reason 160GB hard drives don't actually hold 160GB after formatting. It actually holds only 148.92GB. Marketing, advertising, more for your money. 160GB is easier to say then 148.92Gb, I guess? Looks bigger too.

What its saying is, you can't actually get 1000kb because its binary. 2, 4, 8, 16, 32, 64, 128, 512, 1024, etc. It goes back to 1s and 0s. Thats the way computers think. Think about the MB in your GPU or RAM. Its 32, 64, 128, 256 as well.

For me that's very clear, no problem. I think that if DVD works the same way as hard drives I would accept that, because that how things are, but comparing a DVD to a CD, why a 700 MB CD you can burn the whole 700 MB and a DVD, that the system is almost the same, you can't?

Am I misunderstanding something?



Thanks

With Nero 6.6.0.6 very strange DVD bugs are fixed. Just let you know if you dont have latest version.

[Pretorian]

I'm using Nero 6.6.0.3, so, it's not so old :) .

I talked to people in the store I bought the DVD-R's medias and they said that it should burn 4.7 GB, can you believe :) ?




Thanks

I remember when CD-R's were only 650MB but you could usually squeeze a bit more on them, remeber that the outside of the disc spins faster then the center so as you get to the edge the laser and spindle have to maintain an even burn rate. I'm sure it also has something to do with the difference in the wavelength of the laser between CD's and DVD's as well as the type of dye used in the reflective layer plus DVD's seem to have a much larger Lead in and Lead out then CD's due in part to the DVD spec required for them to play in consumer set top players.

Sounds like the reply you should expect from any mass market pc store.

[Pretorian]

Thanks! :)

I will see what will hapen with the others and if you guys want I can let you know later!

Anyway, thanks for all your help! :thumbsup:
