How do you change VDubMod settings when using AutoGK?

I use AutoGK to burn subtitles into my .AVI videos, my source file is .VOB. I want to shift the subtitles down, but AutoGK controls VDubMod during the whole process. I can open VDubMod in the AutoGK directory to position the subtitles and it creates and .IDX and .SUB, but I don't see how to transfer those settings over to AutoGK so the subtitles display where I want them.

Do I need to convert the .IDX/.SUB files into an .IFO for AutoGK to use?

 

The only control of subtitle position that I know of in AGK, is in the hidden option page (Ctrl F9).

 

Thanks for the info! It still left the subtitles a little bit too high compared to other subtitled videos, but at least I know where the setting is.
