well mtrr is a big difference in memory bandwidth which is a big thing in 
video decoding.
Btw. does the Crusoe support SIMD instructions like MMX, SSE or 3DNOW? 
MPlayer make extensive use of these to speed up decoding.
And if possible you should use XVideo (-vo xv) for output, as YUV needs less 
bandwidth an this supports hardware scaling/colorspace transform. If no 
XVideo give -vo dga -bpp 16 (if you have MMX) or -bpp 15 otherwise. It will 
reduce colordepth for dga output which limits memory bandwidth.
