I was trying to do more of this a couple of years ago, and I got really irritated with the judder that most converters produced when going from PAL to NTSC. I'm not very technically savvy and couldn't follow that complex guide from Doctor M. I preferred the cheating method with IFOedit, as at least my video was smooth when watched on a proper player, and it was easy for my little brain to do. But I just now did a little more research, and it appears this little program might work miracles...and it's freeware!

Everything I read about it says that it perfectly converts and brings the menus along for the ride! I'll have to check it out for a few of those videos that I had to cheat with.
