I tried some muxing test, and I noticed that in order to make wme work
I had first to unsubscribe a boatload of filters: all of Nero and 
MainConcept ones.
Second, I verified that wme, differently to wmp, doesn't absolutely want 
to read
mpegs with a pack size of 2352 bytes (vcd and svcd), so only the usual 
2048 bytes
are accepted.

mpegs generated with a command line as below:

$ mencoder -mpegopts format=mpeg1:tsaf:muxrate=NNN ...

where NNN = video_bitrate+audio_bitrate+some overhead (something around 
5~10% should go,
I used 1600+192 => 2000) seemed to be readable.
I wrote "seemed" because at least wme recognized the file as usable,
but for some still unexplainable reason every file (including mpg 
generated by other muxers and avi/asf/ogm)
I gave it shew an encoding progress but no preview (and was encoded at 
an extremely slow  speed).

Hope it helps,
