Hi folks, me again.

Just finished porting the decoder fragments using the MMX intrinsics.

I had a look at the assembly output and the generated code is anything 
but stellar. I'll do some benchmarks later on to see if it's worth to 
rewrite the code in assembly. With a bit of luck even the intrinsic code 
will be dense enough to sustain the MMX pipeline.

Anyway, is there any good reason not to use the SSE-instructions as 
well? I doubt that anyone would even try to decode a theora file on a 
Pentium-MMX 200 these days. Those parallel average instructions are
