are you sure you do have the matroska full pack installed ? Our full 
pack is coming with the famous ffdshow decoder, a free decoder filter 
based on a library made of the great FFMPEG L-GPL decoders for Linux. 
You are obviously lacking a decoder filter for AC3 audio, thats why your 
first AVI has no sound. ffdshow has all of that, and it won't display 
any DivX logos during playback. This logo is an indication to me that a 
VERY OLD version of the old DivX decoder is still installed on your PC, 
causing the slow playback.

If you do have the full pack installed, can you please check in 'program 
files' 'matroska pack' 'ffdshow' 'configuration' and send me another 
screenshot of the 'codecs' configuration page of ffdshow, so that i can 
see if ffdshow is set to decode stuff, and what ?
