Hm, the command above should work, if you're in the VMGM domain - with
or without jumppad.
I'm not sure, if it works from another titleset domain.

AFAIK, jumppad causes troubles with playability and compatibility and
therefore, the use of jumppad is not recommended. Maybe Scott
discontinued the support for jumppad in the recent alpha versions, but
I don't know.

If you want to jump from within one titleset to a menu in another
titleset, you can do so without jumppad:
Just define a dummy menu in the VMGM menu and store titleset and menu
number in register variables. Should look something like this:

<!-- I suppose you have 3 titlsets, each with 4 menus
     The dummy menu in the vmgm domain is menu number 2
     g4 - stores the desired titleset
     g5 - stored the desired menu number //-->
<vmgm>
 <menus>
  (...)
  <pgc pause="0">
   <pre> {
        if (g4 lt 1) g4=1;
        if (g4 gt 3) g4=3;
        if (g5 lt 1) g5=1;
        if (g5 gt 4) g5=4;
        if (g4 eq 1) {
                if (g5 eg 1) jump titleset 1 menu 1;
                if (g5 eg 2) jump titleset 1 menu 2;
                if (g5 eg 3) jump titleset 1 menu 3;
                if (g5 eg 4) jump titleset 1 menu 4;
                     };
        if (g4 eq 2) {
                if (g5 eg 1) jump titleset 2 menu 1;
                if (g5 eg 2) jump titleset 2 menu 2;
                (...)
                     };
        if (g4 eq 3) {
                if (g5 eg 1) jump titleset 3 menu 1;
                (...)
                     };
          }
   </pre>
   <vob file="empty.mpg" />
  </pgc>
 </menus>
</vmgm>
<titlesets>
 <menus>
  <pgc entry="root"/>
   <vob file="your_menu.mpg" pause="inf"/>
   <button name="x"> { g4=3; g5=2; jump vmgm menu 2; } </button>
(...)

That's it. If the button 'x' in the root menu of titleset 1 is pressed,
a jump is created to titleset 3 (g4=3) and menu 2 (g5=2) via the vmgm
dummy menu.

It's a quick hack, so please excuse any typos in the xml example. Should
work this way, though I didn't try.
