I used VideReMake to merge 2 different DVD’s. This went without a hitch. If I open the file I can see that usually terrible screen that allows you to choose if you wish to play video 1 or video 2. It plays this way with Powerdvd & VLC player.
Unfortunately the file is too large to burn onto a DVD & needs to be shrunk a bit. I have opening the file using DVDShrink & find that it opens OK but that that startup screen isn’t there. Since I have never known for DVDShrink to fail I had burned a DVD before I found out, How do I shrink file & get it to play correctly on a DVD with all of the menus’?
