Video buttons for tgea ?

I have converted the next resource for TGEA :

www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=12471

but now I have a problem why I can compile without errors but the resource doesn't work ...

xoomer.alice.it/afraboni/teamitalia/guiTheoraButtonCtrl.cpp
xoomer.alice.it/afraboni/teamitalia/guiTheoraButtonCtrl.h

Can anyone help me in this convertion ??

P.S. I comment out Mutex call how in the previous resource about convertion from tge to tgea.

Thanks to All
Andrea
