Because this comes from SourceForge it means that this is a program written by anoracks for anoracks. Coming from the school of Linux means that there is no help file or documentation supplied. That would make it too easy. The probability that one could correctly enter the large number of settings is so small that I have decided not to waste my time trying to use this program. It also requires that you process the vob files with several different programs in addition to Gordian Knot. I tried this approach once before and it didn't work then and I expect it would not work now.
