I have a computer dedicated to video editing - which is highly sensitive to all the mucking around an internet connection causes. I have Win XP and a DSL connection. Plenty of hard drives, memory, etc. What is the best way to prevent the internet from making changes? I have tried fire walls, spam blockers, etc. I wonder if a dual boot system - two Win XP or Win XP and Win 98 - would be workable. My thinking is that XP could be used for video editing and the other one for the internet which would keep the editing system clean. Any suggestions??
