[mad-dev] Mad winamp plugin bug

Sorry to post twice in a row, but I've now got a more specific question.  

I've been looking at the mad winamp plugin source code, and I've worked out 
what causes the bug.  When winamp tells the plugin to seek it basically 
calculates a file position to seek to by doing:-

(seekpos / song length) * (filelength).

This works with CBR files but not with VBR files as they have different data 
rates throughout the files.

I assume that the mad library seeks correctly and I would like to be able to 
use it to do the seeking with the winamp plugin (as my alternative would be 
to cludge it by reading frames from the beginning of the file until I got to 
the right time).  Any pointers on what functions I could use in the library?
