Multiples Subpictures & Audio

[speedyrazor]

I have a motion menu with 2 buttons on it, 1 button for 5.1 surround, and 1 button for stereo. I have 2 audio tracks and 2 subpictures on the motion menu. By default when you enter the menu the 1st audiuo track, the stereo audio, and the 1st subpicture is activated, highlighting the stereo button. If you then press the 5.1 surround button, the audio changes to track 2, 5.1 surround, and subpicture changes to subpicture track 2 whilst still playing, ie, I dont want to return to the start of the menu, I want it to continue playing the motion menu while you change from stereo, subpic 1 to 5.1, subpic 2. But I just cant getting it to work.

I am trying to do this like this.

Button 1 (Stereo) = SetSTN audio=1, subpicture=1:ON
Button 2 (5.1 Surround) = SetSTN audio=2, subpicture=2:ON

Track settings below.

Am I missunderstanding something?

Is the menu in the menu domain? That is VMGM or VTSM? If so the SetSTN command will not change the audio or subpicture for the menu. In fact, you cannot have more than one subpicture track (there can be multiple streams for different display modes) or audio in a menu.
If you were to do this in the title domain it should work, but make sure the subpictures are no longer forced (another requirement for menu domain subs).

I have the menu in a Title folder in VTS1. You said "you cannot have more than one subpicture track or audio in a menu." Even if you have got this menu in a Title folder? I have tried turning off forced start, but still doesnt work. Could you give me an example command sequence?

Kind regards.
