AVI(HuffYuv) TO MPEG2 ?

[HOW]

HI

I HAVE A PROBLEM:
HOW CAN I CONVERT .AVI WITH HuffYuv 2.1 CODEC TO MPEG2 ?
MOST OF THE PROGRAMS DOESN'T SUPPORT IT !
BUT IT'S NOT ONLY THIS:
I WANT TO TELL ME HOW TO DO IT WITH FADE SUPPORT !
I MEAN:

I WANT TO PUT FADE IN AND FADE OUT TO AVI AND THEN TO CONVERT IT TO MPEG2.

I WANT TO DO IT WITH ONE PROGRAM BECAUSE IF I USE 2-3 PROGRAMS I'M GONNA LOSE THE HIGH QUALITY OF THE AVI.

ANY GOOD IDEA ??
