You need to understand the process. Factory DVDs are usually DVD9 (dual layer), 8.5GB capacity. What many of us record on are DVD5 (single layer) 4.37GB capacity (4.7). To put something like a 7GB set of files on a DVD5 takes some shrinking. The process is called transcoding.
To do a backup takes 2 or 3 steps depending on what's needed. The first step with a factory DVD is to bypass the decryption. DVDFab HD Decrypter does that task while ripping the files to the hard drive. Some refer to the process as "ripping". The word varies in context. Ripping can be copying the files from DVD to hard drive and not necessarily having to bypass copy protection. Next is transcoding (shrinking), if necessary.DVD Shrink is handy for the transcoding process. It also does minor editing. If transcoding isn't necessary, then all that's needed is the decryption and burning. The final step is burning. Shrink uses supported burners to burn the output or the output files can be saved to the hard drive and burned manually with the burner of choice.
Hopefully that gives you an idea of which step each program is associated with and when to use them. Decryption and burning is mandatory for a DVD backup. Transcoding depends on file size and the target media. It isn't always necessary. In your terms, it can be DVDFab and Burn for files fitting the target media and DVDFab, Shrink, and Burn for files that need shrinking (transcoding) to fit the target media.

I have been using mostly Shrink / imgBurn with Dual Layer Disc's, but my last 10 burns have failed.
Im wondering if I should go back to sigle layer and compression.
what would be a good rule of thumb of compression percentage before there is a noticeabl loss of quality?
All you need for DL is decryption software, such as DVDFab HD Decrypter, and ImgBurn to burn the cleaned source files. Shrink shouldn't be in the mix with DL. There's no need for it and it can cause problems. You use Build mode in ImgBurn for assembling the files and setting the layer break for burning. If not familiar with using ImgBurn manually in Build mode, I'd suggest finding a guide for the process.
Rule of thumb, lower than 70% and you need an encoder. Those with the software usually don't drop below 75-80 before going to encoding. With Shrink, be sure to check all the Quality Settings. I use RB/CCE for backups needing a lot of compression. It works well enough I've not felt the need to back up a lot of my favorites on DL.

hey pacman,
what steps do you use in Imgburn after using DVDFab to rip the movie to the hard drive? i tried to use imgburn after ripping with DVDFab and got an error.
With the files ripped with DVDFab Decrypter on the hard drive,
in Build mode in ImgBurn,
put your Verbatim DVD +R DL in the burner drive,
use Browse for folder to select your source files,
Switch to device output for burning,
under Device set your burn speed,
Under the Information tab click the calculator icon or check the Auto selection to set the layer break.
The Write icon should be ready to go,
click the Write icon and the burn should start.
