the -pp numbers are not identical -pp 15 for the old code is not the same as 
-pp 15 for the new one, sorry, anyone wants me to change it?

for luminance
#define V_DEBLOCK	0x01
#define H_DEBLOCK	0x02
#define DERING		0x04
#define LEVEL_FIX	0x08 /* Brightness & Contrast */

for chrominance <<4

so to compare u must use -pp 15 for the old code & -pp 51 for the new one
if u use -pp 15 for the new code it will not do any chrominance filtering

the rdtsc instructon is used to get the timing info, and its called a few 
times per block if MORE_TIMEING is defined ...
