Oops the 3 seconds one was a typo :)

Ok with .wav it seems to keep consistent timings.

However, using lame "straight" (lame.exe) results in the following timings:

lame1:  00:00:53.28
lame2:  00:00:53.28
lame3:  00:00:53.28

(and the files stay the same size, so maybe lame has fixed their
problem since then?)

This is using the same version of lame that ffmpeg is compiled with.
Any feedback?
Thanks.
