I have no experience with the 'framerate' feature. I will try to look at
the problem with my Flea (Thanks PtGrey!) but I can't promise when this
will be done.

This feature is rather new (IIDC 1.31). The classic ways to determine
the framerate are
- for Format_7: use the byte-per-packet (BPP) value
- for other formats: use the framerates specified by
dc1394_video_set_framerate (15, 30, 7.5,...)
