Sorry for not really involing myself in your prior 2 dvds to 1 dvdr threads.
I’m sure your Menu has help many, but I dont like menus that just says Movie 1, etc without the actual movies name. My movies return to the Menu when finished.
I author my 2 movies in Maestro (you can also use DVDLab almost the same way). I make my front Menu from the front covers of the 2 DVD’s in question ( the menu is just a simple JPG file made in Paint Shop Pro) either scanned or if I’m lazy just download from IMDB.com. I also then move the 2 pics together to make a front cover as well. I tend to use the VHS covers as they a long and narrow and about 1/2 the width of a crystal case cover (I dont store my backups in those big bulky dvd cases).
In Maestro (and DVDLab) you just direct the end action of each movie to run the menu again, even back to their own button if you wish. You can also have a small intro movie before the Menu, the skys the limit really.
I know the way I do it involves authoring, but then all my double movie dvdr’s dont look the same, have an actual title (and graphics, can also be annimated as well) and all done in a few minutes. But I supose its easier for me as I dont make the original encoded movie with DVD2One or Shrink or what ever. I always use CCE to do the encodeing and get very little loss in quality. It produces *.mpv and *.ac3 streams ready for authoring rather than *.vob files from those all-in-one quick solutions.
Each to their own, but I find authoring them provides the ultimate in flexability.
I hope someone can help with a solution to your immediate problem.
