Not all of these will use it. mplayer uses it, and I believe someone mentioned using it to send midi clock. It isn't used for general timing, I believe the system timer interrupt (irq 0) is used for that. I just enable it in my tests because it's likely to be enabled on a DAW, but I don't think any of my current software uses it much. Lee
