Can Adobe production Suite 5, output any high definition format to a hard disk, WITH DVD menus and chapter selections intact? I'd like to be able to playback this output from a hard drive with DVD style navigation intact.
Ideally, I'd like to output to flash with DVD menus intact. When I tested this earlier Encore rendered the video stream but no menus.

If Adobe can't do this, can Vegas Pro?
I am sure I am missing somthing obvious, so thanks for the help.

If neither can, then maybe someone could offer an opinion as to why the cability is not availabe.

Not sure what you want but you can burn a BluRay iso on a DVD disk instead of a BD disk.
The BD iso you make with Encore and burn this to dvd with e.g. Imgburn or Nero.
About 20 minutes timeline will fit on a dvd.
You can play this dvd only on a BD player.

I've never tried it, but Encore is supposed to be able to export your project to Flash with the menus intact.

Another option is to choose "Blu‑ray Folder" as your output option, which will function like a Blu-Ray disc, but from the hard drive. You can play it back in a software Blu-Ray player
