MSACM: winemp3 codec crashes on seek, reimplement with libmad?

[Alex Villací­s Lasso]

I was trying to exercise the winemp3 builtin codec using a Visual Basic 
control that essentially implements the Windows Media Player look 
(MSDXM.OCX). After specifying native quartz.dll for this app, I tested a 
few AVIs with mp3-encoded soundtracks. What I can notice is that the 
sound has very annoying jitters, and in addition, it crashes on a seek. 
Some people have noticed the jitters too 
(http://bugs.winehq.org/show_bug.cgi?id=3853). However, rather than 
trying to fix the wine fork of mpeglib, I was toying with the idea of 
reimplementing the codec as a libmad (GPL) wrapper. Are there any issues 
I should take into account before trying this?
