FFmbc 0.6-rc7 -ss -t don't output complete frames of audio

[GoogleCodeExporter]

What steps will reproduce the problem?

Encode some DV in a MOV

Split that MOV at places that should be seamless edits

ffmbc -i primary.mov -ss 2 -t 3 -acodec copy -vcodec copy 1.mov
ffmbc -i primary.mov -ss 5 -t 3 -acodec copy -vcodec copy 2.mov

Here I'm working in PAL 25 FPS 48K audio.

I would expect exactly 75 frames of video and 144000 samples of audio. I am NOT 
getting the correct number of samples of audio.

Using, for instance, "Atom Inspector" on Mac OS X I can see that in 1.mov there 
are 144384 audio samples (too many) and in 2.mov I can see that there are 
143360 audio samples (too few).
