mmpython will help but not always.
Lets put it this way. I will ALWAYS read through the whole file. In that
order I don't mind evaluating each frame. The thing I don't seem to be able
to find is the timelength-constants for frames for the different mp3
versions, bitrates and layers. Can anybody help me?

Thnaks,
Ivo
