Thanks for the thorough reply. I downloaded the second latency checker (resplendence) and it’s telling me there is a problem and to check for bios updates and cpu throttling. The firewire is new and it has the TI chip, thats why I bought it. They claim it works with win 7 64 bit. Their drivers come with windows, no updates. I dont have a lot of time but I’ll read up on what you linked and everything you suggest and post back later. Thanks again.
