Svcd blank subs stream removal?

[neo_tech]

Hi everyone,
for many days i was looking of some way by which i could make selectable subtitles for my svcd which i made from an AVI file. then after days of search i was successfully able to do so using Subadjust, MaestroSBT and Winsubmux. after burning my SVCD i played it into my dvd player and voila! it worked. i was able to select the subs using my dvd player's remote control...exactly what i wanted.
what i wanna ask here is that i have added just 1 single subtitle(english one) in my svcd using winsubmux leaving the other 3 streams Unchecked in it. so accordingly those 3 streamings should be non existant while playing in the player but when i play that svcd in the dvd player then the 1st stream selected shows the subs that have been added but again pressing the subtitles key on my remote shifts to the 2nd track which is empty..again then 3rd and similarly the 4th track...after that the OFF option comes...so i want that right after the 1st track the next thing which should come should be the OFF option of the player as the other 3 streams r not being used...or if i would have loaded 2 sub streams then after the 2 streams the 3rd option should be the OFF option of the player.
in short how do i remove those blank streams from my svcd.

Thanks

just wanted to make things clear. if theres no way out to this issue then i'll have to put something like N/A as the subtitle for the other 3 streams coz if someone presses subtitle key and goes to 2nd 3rd or 4th sub stream and finds nothing then he might get confused. putting N/A will atleast make the person known of the fact that these streams don't contain subtitles.
