Hi,

I have a couple of special films that I want to make back-up copys of - but I'm having difficulty understanding the DVD capacity thing.

They are both commercial format.
One film is short and when I've copied over an ISO onto HD - the ISO filesize reads less than 4.7GB which is the capacity of a DVD-RW SL.
So, writing an ISO to a standard DVD-RW SL is no problem for the short film.

The other one however is about the same standard as any commercial DVD and copies over at around 7.9GB - which of course - at least as I understand it - won't fit on to a standard 4.7GB DVD-RW SL.

From copying rented commercial DVDs onto my PC -
(so if I dont get time to watch it the evening I've rented it, can leave the DVD back and watch it later in the week - without having to fork out again) -
I notice the file size is around the 7.5-7.9GB mark.

The special film - well its a film on the Life of St. Bernadette - that I bought in Lourdes - I want to make a back-up copy of - incase something happens to it -
is, as I've said above around 7.9GB - so I presume it won't fit onto standard 4.7 RWs.
This leads me to conclude that the format for Video Shop commercial DVDs is the Dual-Layer format - Max Capacity 8 something GBs.

Am I right? do I need Dual-Layer DVDs if I want to make a back-up copy of this film - or have I missed some compression issue.
I know that there is software out-there that can 'compress' commercial DVDs unto ordinary single layer DVDs at a certain percentage quality.
But as I don't copy alot of DVDs - rarely infact - I don't want to fork out for it.
I have a copy of a freeware ISO copier that will do simple straight copies.

But I'm wondering - are standard commercial DVDs for films single layer DVD-Rs and use a compression format that comes out at over 7 GB when writing an ISO with an ISO copier app?
Or is Dual Layer the Video commercial standard?

Dual Layer DVDRs - believe it or not - are like hens teeth where I live.
Never mind Dual Layer DVD-Rw's which I've never clasped eyes on.

Sorry if this sounds long winded - I'm a bit of a DVD Noob.

Peace
Ausser.

Hi, Ausser

[Sharp]

I use this http://www.dvdfab.com
It rips encrypted disks, trancodes, and burns. One program that does it all with no input from you.

All you need to do is decide on what you want to rip, which should only be the movie if your planning on burning to a DVD-R

Regards.
Sharp.

Thanks guys - i'll look into those..

I have the infamous DVD - Decrypter - if any of you ever heard....
I think you have to hunt hard for it on the net now...
It was one of the 1st rippers on the scene - then the author disappeared for spooky cloak and dagger reasons...

But can anyone tell me for sure if the standard commercial DVD format is Dual Layer - DVDR?
I just always presumed it was single layer DVDR - until I saw most DVD ISO rips at over 7GB - which is in excess of SL DVD R/Rw - yet I'm not convinced somehow...
See - that would mean that older SL DVD players shouldn't be able to play commercial DVDs.

Peace
Ausser.

Hey - I see something about DVD9s > DVD5s

So DVDRs and DVDRws that you buy in the shops are DVD 5 format then?
And commercial format is DVD9 - I presume?
But neither DVD5 nor DVD9 are Dual layer - I presume...?

?

Peace
Ausser.

I have DVD Decrypter and many other freebies sitting in my archive folder.
There are many commercial and free programs out there, so go with what works for you.
