To my experience, speed does not drop any frames. Like movies are shot in 24 fps 
and shown in PAL land with 25 fps by speeding up (and without repeating frames 
e.g.).
What I do is to revert this progess (making 25 fps TV records 24 fps again.). 
The smart thing when using the speed option is that the audio gets converted too 
to the proper length needed in one step.I only know sox or a very old but still 
genius program for windows called BeSweet which could do this job either.

I have no problems with ffmeg taking the place of mencoder and I'm looking 
forward to test filters coming. That is the only thing I can contribute, my 
programming knowledge is too poor. But it is good to hear that there is a chance 
that mencoder will work until things are ready for a complete take over.
