I remember Amithlon before the licensing problems, running on (if memory serves) a 750mHz x86 machine. Display was a 38 inch (yes, that's right) monitor, & it was streaming & playing four videos (using Frogger) from the same HD at the same time. Awesome ! 
. 
running 4 videos at the same time is not a miracle
in fact winuae can did it before amithlon
check this screenshot on aminet

readme file says moovid instead frogger
