Could be a overheating problem for one as video edting takes up a lot of power and time but I think it might be more to do with the software you are doing your encoding/editing with. If encoding from avi to mpeg, it can take whole night depending on your comp.and the size of the recording. I have HT and a 2.8 Cpu (800fsb) and believe me the encoding process can take a lot of time. Try shutting down any progs. running in the background. Just a couple of suggestions. Others with more experience would, I am sure, try to help.
