Daewoo S2122, SVCD Subs

[Yewflo]

I have problems with selectable subs in SVCD on my Daewoo S2122. On the campatibilty page it says it can do it. But how?

I used WinSubMux in the DVD2SVCD-package, and everything seems ok, and everything works on the player (2 audio tracks, the picture, synchronization and so on) except the subs.

Please help
