VTS_01_0.VOB would contain the video for the first titleset's menus.
But the first titleset has only one menu and it has no video.

I have created discs like this and didn't find any compatibility
problems.  However, I only used a pre-routine in the titleset menu.  You
also have a post-routine, which will run after the menu's video has
played, but there is no video to play and I suspect that is the source
of the problem.  Try replacing:

with:

    <pre>
        if ( g3 eq 1 ) { g3=3D0; jump title 1  chapter 1; }
        if ( g3 eq 2 ) { g3=3D0; jump title 2  chapter 1; }
        if ( g3 eq 3 ) { g3=3D0; jump title 3  chapter 1; }
        if ( g3 eq 4 ) { g3=3D0; jump title 4  chapter 1; }
        if ( g3 eq 5 ) { g3=3D0; jump title 5  chapter 1; }
        g2 =3D 1; jump vmgm menu entry title;
    </pre>

Why do you have a second titleset with only menus?  It seems like it
would be simpler to put those menus in the VMGM.
