The problem with ASIO overload is that there are so many things that can cause it. So far I think I have ran into 4 or 5 myself. I am running XP on a PIII 667mhz. Here are a couple of things you guys might look at if you haven't already. Hardware exceleration for your video. Depending on your system you may have to turn it down or all the way off (this is Logic 101). Next check your device drivers for your audio and MIDI interfaces, make sure they are the most current. I also found (in XP anyway) that combining devices from to may diferent manufacturers can be an issue. I got rid of my MOTU MIDI interface and bought a Midiman (which is who makes the drivers for my sound card) and no more ASIO problems. I also had to many tracks set up in logic for the amount of devices my sound card would allow. I also had problem with one particular song and chased that down the the fact that I had acidentaly saved the files to my 5200rpm hard drive which could not keep up, as I got into full productions with plugs and all. I am sure that there are a couple of others but I can't remember now. If your system is not optimized for audio you definatly want to do that. Try videoguys.com they have an extensive list of tweaks for win 2000. I hope something here helps. Iknow it is frustrating Good Luck Tod
