You can modify the gst-launch command line in the script to read something 
like this 

 ... ! videorate ! video/x-raw-yuv,framerate=\(double\)25.0 ! 
ffmpegcolorspace ! theoraenc ! ....

then it should work. Thoggen does that and seems to encode mpeg files with 
variable framerate just fine from what I've heard.
