I assume it's a DVD5 but don't know, do you need to check that for any disk you want to copy? And if so is that info gspot will provide?

It copied as a videoTS folder with the vob files inside.

Go to "My Computer" (Windows explorer), right click on the DVD drive, go to properties. How big is the disc?

5.89 GB size

That's a dual layer disc. You have to do one of two things.

1. Copy DVD 1:1
Rip it again with DVD Decrypter, and be sure to go into the program settings and enable the MDS file creation checkbox. When it rips the disc to an ISO+MDS file pair, then burn the new disc with ImgBurn. You'll pick the MDS file as the thing to burn. You need to use a Verbatim DVD+R DL disc.

2. Shrink Copy.
You'll rip the disc in DVD Decrypter, then use DVD Shrink to "shrink" the DVD to fit a 4.37GB DVD-R or DVD+R single layer disc. You may lose some quality with this method, it's not 1:1. How much quality loss is noticed (if any) depends on how bit-saturated the original retail disc is.

MDS create file box checked, re-ripped to folder I created on HardDrive, ripped with no errors, put in DL DVD disk, try to copy and there is no MDS file, did this twice, it is not creating the MDS file, even chech file extensions and MDS is checked there too.

You see filename.ISO, but no filename.MDS?
Hmmm....

Well, you can always just try burning with ImgBurn, and let it guess at where to put the break. There's usually not a lot of locations, and ImgBurn is usually correct.

If you play the disc, and it can't access the second layer, then you'll know there's an issue.

There is no .ISO or .MDS, it has the vob files and a couple of other type of files...like it just copied what's on the disk, maybe it didn't decypt....but it did burn using dvd shrink.

You ripped it in file mode --

File mode takes the VIDEO_TS folder, and all the IFO, VOB and BUP files inside of it. This is not what you want to have.

ISO mode create an ISO and MDS.

You know, up at the top of the program ... FILE, EDIT, MODE
and then be sure you're in ISO mode.

This is in DVD Decrypter.

Although DVD Decrypter can burn, you're better off using ImgBurn to burn.

Ok...I should have figured that out...

What is meant by "no reference position found" ? I thought the disk could not be played because dirty/scratched but I guess this is the reason it won't play and is there anything that can be done?

The dvd drive in the computer shows 0 bytes...do factory movie disks get out with nothing on them?

I don't know that I've ever had that error message.

If this retail DVD is copy protected, it may use a method that DVD Decrypter cannot understand. DVD Decrypter was discontinued several years ago -- the developer decided to concentrate more on the burning aspect (hence, ImgBurn) and not so much on the reading/ripping of discs.

Newer software, that can detect newer protection schemes, is DVDFab 6, and you can use it in the free "HD Decrypter" mode. Download it here: https://secure.avangate.com/affiliat...www.dvdfab.net

0 bytes is probably related to the protection. I can't think of a likely scenario that would create a blank pressed DVD. It's not like a burn, where you could overlook one or get a lead-in burn fail that goes unseen. A blank press? Nah.
