Hello,

I send the current working trace of VLC. It is almost the same that the
non working except it is passing the stream_Peek function. There is
stream_Size==0 like in a VLC ASF stream (well, it is what I assume but I'm
not sure as always). There is also my own debug traces in it. I'm not sure
there are relevant for you but anyway :-)
Here it is :
