DvD Decypter Ver 22.214.171.124 is old. This version was the last version done before it was discontinued. DvD Decrypter 126.96.36.199 Found here.
Better to use DvD Decrypter in Iso mode. Because the program is no longer updated. Use of AnyDvD with it will remove the latest copy protections.
Always Iso write to the desktop. Once you have a image to your desktop you can decide what you want to do from there.
If you need to shrink it to fit one a single layer disk, then you can open up the iso with DvD Shrink and shrink it. Save as an iso. Use Imburn and iso write to your blank media.
If you need to burn it to Dual Layer, use Imgburn. Iso write to you blank media.

I have never used IFO mode myself, so I am not to sure if you can recover that data. My first instinct would tell me to reopen them with DvD Decypter and save them as an iso. Then open the iso with DvD Shrink.
When burning to Single Layer media use -R
When burning to Dual Layer media use +R DL and change the booktype to DvD-Rom.
