I use Adobe Encore to author, which I don't suggest to anyone. A lot of the shortcut keys are different than other Adobe programs (for example, Ctrl+ to zoom in), and it doesn't feel very Adobe-ish, so I suspect that they may have just purchased the basic program from an upstart somewhere and then dressed it up a bit. The main problem is that I have really bad problems with it crashing, and I can't get a large, complex disc to compile it in. What I do as a work-around is build the discs on my main computer and then transfer over to the laptop to compile. The laptop doesn't have a dvd burner, so I have to burn all the vob's to cds and then put it back together on the desktop. It's better than just swearing at the computer when it crashes, which was the original solution.
Kind of amazing what I'll do just so I don't have to learn another program.
Let me know about the disc.
