You mean xineplug_dmx_avi.so? That's just the AVI demultiplexer which 
unpacks the audio and video data out of the AVI container. But 90% of 
CPU time is spent in the decoders, so the xineplug_decode_* are the 
most interesting. You can learn from the stream info window (open up 
the menu by right-clicking in the video window or the panel and select 
Stream->Window information...), what codec the video uses.

This will only help, if you have background processes running.
