Hello again,

after I checked my installation, I believe the problem (if it is the 
mismatch I described) is not a problem of XviD itself, but of different 
versions installed, such that a different codec is used for encoding than 
for decoding. 
Could you check your Windows to ensure that only one version of XviD is 
installed (the latest)?
