Well, AssumFPS would alter the running time and as I explained previously, I didn't want to change it, as things would get ugly really fast if I had to start messing with audio :P
Oh, I see that I did say "playback speed" at one point. My bad.
Whether I put "interlaced=true" or not, I still end up with progressive video. Because of suggestions from different guides, I did tests both ways, true and false, and I liked the results from "interlaced=true" better.
The good news is that it's almost complete.
I did keep boon's menu from the original version's SL NTSC DVD that is at fanedit.info but everything else is newly encoded - including the extras :D
I'll post an update soon.
