Using that cli, do you still experience  blocks in black areas? Using 
scplx_mask=0.2 and mbd=2  most of them go away for me,
but some are still left. Maybe tcpl_mask will remove them?
I'm searching a definitive solution :)
mbd=2  gives me much better quality than vhq, and it also seems to lower 
the bitrate; I wonder why it's not enough emphasized in the
Finest Manual
How many fps do you get?

Thanks,
