I repeat all tests on another machine (P750+TNT2) and there are 
slowdown too :(

examples:

Ronin trailer:
[DIV3]  640x304  24bpp  25.00 fps  820.6 kbps
cvs.010724: V:  24.178s VO:   9.157s A:   0.000s Sys:  17.702s =   51.037s
cvs.010725: V:  25.362s VO:   9.210s A:   0.000s Sys:  17.808s =   52.380s


Star Wars Episode 1 trailer:
[DIV3]  640x288  24bpp  24.00 fps  995.3 kbps
cvs.010724: V:  27.658s VO:   9.945s A:   0.000s Sys:  19.771s =   57.373s
cvs.010725: V:  29.194s VO:   9.944s A:   0.000s Sys:  19.644s =   58.781s



maybe this problem exist only on FreeBSD ?

best regards
