I have no dog in this fight because I run an NVR. If you find something better than BI I'm sure there are a lot of people here who would like to know about it. There haven't been any better alternatives suggested because nobody knows of one. My own input is that if 100% cpu usage overheats a system, there's something seriously wrong with that system. I'm assuming you've used Task Manager to determine that BI is the cause of the high CPU usage, you're not thrashing the swap file, and anything else that could be suspicious.
