ToonBoom 16 Exporting Problems/FPS

The FPS won’t stay at the speed I want it to go in. I want the speed at 8 frames per second but once I export it WMV it speeds up to 24.
I did save it and it plays well within ToomBoom but when it plays in Windows Media Player it speeds up.

You can’t set the FPS in the movie properties. The fps setting used will
be that of the project itself. Make a copy of the project and set the copy
to 8fps (menu-Scene-Scene Settings: resolution tab).
