I've not seen that and I just re-encoded all my stuff to take advantage 
of 2 pass (using static x86_64 linux bin) - but I have seen audio/video 
issue going from mjpeg to ogv. I solved that issue by importing the 
mjpeg avi into kino and saving as dv and then using ffmpeg2theora.

I assume by .mov you mean h.264 w/ AAC ??

What happens when you export from FCP to mpeg2 and then run 
ffmpeg2theora on that?

For the record, I've not had any problems using older libtheora based 
players on ogv made with latest ffmpeg2theora.
