Hi PROs, This may be basic, but I want to be able to position my subs exactly as I want, anywhere I want, in the frame. In a 16:9 movie, I'd like my subs to be entirely in the lower black bar, leaving the picture area completely free, for example. Experts have assured me that VobSub can do it, but I don't know what the red square really means, or exactly how to use the sliders on the right. As a matter of fact, that's about the only feature of GK that I can not enjoy because of my lack of knowledge. Most of the guides (on anything) I have come across do assume a lot of knowledge in the reader and take an awful lot for granted (one notable exception is the one on AutoGK by manono - check it out). Even remembering Rule 1, I couldn't come across one on positioning the subs that really goes into the depths. Regards.
