Hello everyone. I'm still fairly new to DVD Authoring, and I was wondering if someone could help me with my first multi-audio, single-subtitle menu in DVDLab Pro.

Basically, I have 2 audio tracks, and 1 subtitle track. I have a series of 4 menu's, linked to each other, and each one signifies a different audio/subtitle selection. Once you hit the menu, the precommand is accessed, and the selection should stick. The precommands for each of the combinations are as follows;

Audio 1, Subtitle OFF

GPRM0 = 0
GPRM1 = 0
SetSTN (subp=GPRM1ff )
SetSTN (audio=GPRM0 )

Audio 1, Subtitle ON

GPRM0 = 0
GPRM1 = 64
SetSTN (subp=GPRM1ff )
SetSTN (audio=GPRM0 )

Audio 2, Subtitle OFF

GPRM0 = 1
GPRM1 = 0
SetSTN (subp=GPRM1ff )
SetSTN (audio=GPRM0 )

Audio 2, Subtitle ON

GPRM0 = 1
GPRM1 = 64
SetSTN (subp=GPRM1ff )
SetSTN (audio=GPRM0 )


From the main menu, I have it linked to a VTS VM command that, theoretically, checks the Audio/Subtitle setup, and then changes the menu accordingly. So, when ever you hit "Setup", it goes to the command, checks the current setting, and links you to the right menu. The command is as follows;

GPRM0 = 1024
SetHL_BTN GPRM0
GPRM0 = SPRM1
GPRM1 = SPRM2
GPRM0 *= 100
GPRM0 += GPRM1
if (GPRM0 == 64) LinkPGCN 4
if (GPRM0 == 100) LinkPGCN 5
if (GPRM0 == 164) LinkPGCN 6
LinkPGCN 3

Now. Here's the fun part. If I use the audio selection in the menu's, they stick. ie; It's on audio 1, I hit 'Audio 2' and go to that menu, when I play the movie, it's audio 2. However, the subtitles are defaulted to "ON", and even if I select "Off" from the menu's, they won't actually turn off. However, if I'm playing the movie and turn the subtitles off with the remote, THEN go back to the setup menu's, they're listed as 'off'. So basically, it accurately checks what the setup is, and changes the audio. But for some reason the subtitles just won't change from the setup menus.

The model I based it off of (which can be found here): http://www.mediachance.com/dvdlab/tutorial/amanager.html And the only thing different I can think of doing that I haven't compensated for is something in the VM command. That model used 2 subtitle streams, I'm only using one. I don't understand why when I select a menu with 'Subtitle off', they don't turn off, since the precommand should work as soon as the menu is opened.

Any help would be greatly appreciated. I love this program - despite a few bugs I've encountered on test compiles - but the real reason I wanted to upgrade from the first DVDLab was for the optional multi-lingual features. Here's to hoping someone knows why my menu is messing up.
