Too many other mechanical hard drives to count. And my "spare tire" is a 10 year old Dell 8300 running Win XP.
I know Geoff is an expert on PGCEdit and I tried to study it at one time but it was beyond my limited time and brainpower to learn it. So that's when I upgraded from the Studio menu maker to Adobe Encore. Encore will do anything that you can see in a commercial dvd. That includes hidden buttons, easter eggs, all that stuff.
It sounds like what you want to do is make chapter playlists. For example, if you were making a tutorial dvd that had 10 chapters. You could set it up to play 1,3,5, and 9, or 2,3,7,5, 1, and 8. That's not a typo, you could play them in any order, as many ways as you like, as long as you have room to put buttons on your menu.
But before you can make playlists, you have to set chapter markers.
I don't know anything about Sony Movie Studio but you might want to look for chapter playlists, or just playlists.
Also, the standard for dvd vob files is 1GB or around 1,048,000,000 bytes, give or take. You will never see anything larger than that on a dvd. So the 1.63GB size is not right and probably won't work if burned to a dvd.
I'm always on the lookout for old movies. Sometimes I find them in PAL format, xvid, or avi. What I do is use TMPGEnc Xpress to convert them to dvd compliant mpeg-2 NTSC files. From there it's a simple matter to create a basic or fancy menu and burn a dvd.
