Video extraction on Mac OS X 10.4 using Tystudio

Just wondering if anyone has been able to set up and use Tystudio under 10.4?

I can get the application up and running in X11; however, it crashes as soon as I try and convert video.

Tystudio will allow me to copy a .Ty file to the local machine but won't edit.

I was getting errors in the X11 crash log about a library file not being loaded so I reinstalled X11 but still no joy (I'm at work so I don't have the exact name of the library to hand).

Can anyone help?

Thanks is advance.
