Max file size (overburn) with Nero

[poerschr]

Why is it that Nero will bun a image file that is about 780MB, but will not burn a video file in data mode that is 720MB even with overburn enabled?

I even tested overburn in the testing part of NERO. It found that my drive and CD-Rs would only hold 716MB, but I knew this to be wrong. I tested it with VCDeasy, and easily was able to burn 820MB onto one 80min CD-R (mabe even 830MB). I used to make SVCDs like this all the time! But with Nero, the damm program does not want to overbunrn correctly, except on the image file mentioned above. Wierd.....

Thanks....

The reason that you can burn more to a CD in video mode is because a VCD lacks all the data error protection laid on on a data CD. Therefore, a disc burned as data will hold less than a disc burned as data.

You can buy 90 and 99 minute CD-Rs now, or even better - DVD+/-RW drives have falled drastically in price. They're a great buy - I haven't looked back since I got my Pioneer DVR-106.

Hope this answers your question,

"a disc burned as data will hold less than a disc burned as data. "

I guess I don't really understand what your saying....A disk burned in data should not have the error protection. It does not matter if I am buring a DIVX data disc, or a disk backup, or a cd cue file...both are data.........I think that maybe a data disc in Nero still uses the error protection, how can I turn this off??

?????confused

Sorry - I mis-wrote that! It should have read "a disc burned as data holds less than a disc burned as VCD".

I don't think you can turn the error protection off - it is part of the Data CD standard. A DivX burned to a CD is still data, although it is a video file. VCD is a different standard of CD.

Basically, you can't change it.

ok, I take two image files, one is a bin/cue file and one is a iso file. The bin/cue file will burn onto a disk perfectly at 780MB (without any overburning message), while the iso file will not burn onto the disk at 740MB, Nero tells me (overburning message) that the file is too large to fit on the disk. I still don't understand, what is the difference???????

[Cobra]

The ISO image is for a data disc. The BIN/CUE file is an image file of a Video CD.

Video CDs do not use error protection. Data CDs do. Error protection takes up space.

Therefore, you can fit "more" data onto a Video CD than a data CD, because it is not "padded" with error protection.

If you took the 780MB .DAT off a Video CD and tried to burn it as a data CD, it would not fit! This is because you are burning it as data.

Data CDs and video discs are two different standards.

I understand that.....but the bin/cue file was not a video cd backup, it was a backup of some software..(maybe I didn't make that clear to you, I apologize)...I created the iso file, of the divx video I am trying to put into a cd...The bin/cue file works fine, while the iso file does not work....Why? Both are data??? Forget about the video cd, I understand that point, but why is it that one data backup will fit perfectly on the cd and the other will not?? Is it not the type of image file, but the two should do exactly the same thing? And yes, I used exactly the same media...

[poerschr]

btw, thanks for all you help....

[Cobra]

To be perfectly honest, I don't know. Maybe BIN/CUE files already have the error protection on them, and all Nero does is burn it bit-for-bit. The ISO might not, and requires that it be added in.

How big is the total of all the files contained within the BIN/CUE image? That could hold the answer.

When it comes to burning disks a bin/cue file = a Video disk and an iso file = data file. Doesn't matter what is really contained in the file. No big mystery .Since a Video file lets you put more on a disk then a data file you now have your answer.. There maybe a work around but I don't know what it is.

[poerschr]

I am not dealing with any video files!!!! Both are data..one works the other does not Why??

(1) bin/cue file = 780MB (all data)
(2) iso file = 740MB (all data)

(1) works, (2) does not

Quote"The BIN/CUE format stores a lot more information about the contents of the CD: instead of 2048 bytes/sector as found with the ISO format, the BIN/CUE images use 2352 bytes/sector. This extra information allows for error checking/correction and makes life a little easier when it comes to overcoming copy-protection schemes. Additionally, BIN/CUE images are split into two major categories (there are more but they are horribly obscure and probably almost never used): Mode 1 images typically are data-cds while Mode 2 images are for (super)video-cds. Both 'types' of discs use 2352 bytes/sector.

@johns0
Great, that is exactly what I was looking for....Finally my question is answered...Thank you very much.
