I think this will cause problems with the directshow filters I did.
Currently it uses some hardcoded defaults of 128Kbit and CBR, I haven't
tried this patch so I don't know for sure.

Using directshow to convert a nuv file to avi (no recompression, direct
streaming) will probably make the avi file contain invalid information about
the mp3 stream. Maybe it will cause problems on normal playback too.

So I think that it might be nessesary to extend the nuv file format to
contain atleast the bitrate and if its cbr/vbr/abr.
