My desktop running 7-STABLE with 100Hz and NOPREEMPT (it's a 4core SMP system),
I tested 8-STABLE, but that is not too responsive, the solution is:
100Hz NOPREEMPT + kern.sched.preempt_thresh=224
After this setting, the system is likely responsive as 7-STABLE.

Normally, decoding video would not be considered an interactive task,

You have to be root to use idprio, requiring a suid wrapper,
which strikes me as kludgy.
The worst part is that idprio and rtprio don't entirely work.
An idprio process can still interfere with a rtprio process. :-(
