I am one seriously happy dude! We are good to G.O. on the subtitle front. Managed to suss it out in DVD Lab Pro itself, and got exactly what I needed! So I went through half the movie today, writing down the timing, whapped the times into DVD Lab Pro, burned off a test copy (the number of discs Ive used on test copies alone must be ridiculous), and hey presto, it works! And it looks bloody spot on to...top notch stuff.
So, we finally hit the home strecth. Half a movie left to subtitles (no more than 3 or 4 hours work), then onto the actual DVD authoring. Just working on a few ideas now for menu backgrounds. Won't be a very elaborate thing, my menu's never are. Although I am at least planning to put a disclaimer at the beginning of the discs, just haven't decided who's to steal/use yet?

In short, not long now gang.....
