Can Encore CS5 or another Adobe program export a formats that are not DVD (not *. IFO / *. VOB), but with the "Menu" function.
A menu with links to movie, image slideshow that can be played from the hard drive on Mac and PC computer?
For PC, you can build to a Flash format in the Encore build tab. There are some limitations.
For either, you can build a regular DVD to a folder, and play that on PC or MAc. That assumes you have capable player. You can also do that building to an iso image, but the player must support that or you must "mount" the iso with an app for that.
