Will a DVD+R hold 4,700,084,224?

[Matthew]

I've done this backup and the size of the vobs/ifos is 4,700,084,224.

I know this is fine for DVD-R but can anyone confirm that this will fit on a DVD+R? The FAQ just says that DVD+R holds "about 4,700,000,000 bytes".

I'm just being precautionary in case in future I want to make a copy onto a DVD+R single layered disc.

Thanks :)

My Verbatim 4x DVD+R say 4,700,372,992 bytes, but it may vary a bit from one manufacturer to another. I only have Verbatim +R, so I can't check that.

Thanks for the reply.

I plugged that number into google and over 2 pages of results were returned so it seems credible.

However, it would seem to apply to image size not VOB/IFO size? Because the image is actually 4,700,973,056 *sigh*

Here is what DVD-R is:

4.383 GB
4,489 MB
4,706,074,624 bytes

Can someone fill in the rest for DVD+R and confirm the bytes. Thanks.

This is funny. DVDDecrypter reports for
Verbatim DVD-R 4x: 4,706,074,624 (2,297,888 sectors).

But when I start burning, and the size is below 4,707,319,808 (2298496 sectors), DVD Decryper warns that the disc may be too small, I press 'ignore' and the drive starts burning....the very same happens with Maxell 2x and Taiyo Yuden 4x. I have recorded one with 2,298,233 sectos:

This is a recorded Taiyo Yuden, where the size originally also was reported as 2,297,888 sectors:

alexnoe, on the px708a?

[alexnoe]

yes

[Barker]

your plextor overburned the ty then right? ( hence cannot copy back to the verbatim which doesnt overburn as well )?

I dont kn0w.

[alexnoe]

It works with all discs. I wrote a similar size to a Verbatim...I don't know if it is 'overburn': It takes the physical size as capacity, instead of the number of free blocks.

[Barker]

this is why plextor are the #1 drive available...
