I keep on seeing these "Blackbox" apps like Tivo using Linux but the fact remains the average folks cannot get any reasonable kind of A/V performance and support under Linux. That's what we need.
Needing to save money and get some fast cash (I'm unemployed), yesterday, I swapped out my dual P-III motherboard in my BeOS box for a Via C-III (700MHz) based system. And I got my first real hiccups while using the OS when I was playing MP3s and _launching_ the TV program _full screen_(640x480 on 640x480 virtual desktop window).
Obviously, when this stuff is done right, more CPU power can only help, but it still has to be done right. As I am sure that you know, BeOS claims average latency of 250 microseconds.
