Hi, after read the article you mentioned, I did the following: 1. deinstall 
all other libdivx-related packages.
2. install linux-divx4linux4 under multimedia port.
3. exec transcode, but it complain it can't find libdivxdecode.so, which is 
under /compat/.../lib,
   so I make a sym link from /compat//... to /usr/local/lib, and than it 
complained not to find ld-linux.so.2 which is also under /compat/..linux/, 
so I made another sym link to /usr/local/lib, than transcode again.
4. it workded! start to remux my avi, after it's done, the file became 1.2G 
while it's 745M before remux. I guess it's because it encode mp3 into PCM 
(or whatever). Exec output:
[transcode] auto-probing source test.avi (ok)

5. I use avifix -i foo.avi to check new file:
> avifix -i foo.avi
[avifix] scanning AVI-file foo.avi for header information

[avilib]    132589 chunks, 509141760 bytes
it seems like both video and audio have the same chunk. 6. split it with 
avisplit.
avisplit -s 700 -i foo.avi:
[avilib] V: 25.000 fps, codec=DIVX, frames=132589, width=720, height=576

7. play with xine, they both have correct sounds!

thank you very much for your help! now I can put it to CD and save some 
space!
