I am trying to convert avi files and burn them using nero 8 vision. I have an HP pavilion with amd 2.08ghz 1g ram 120gHD Hp940d dvd burner using winxp. all drives in dma ultra 2, scout disabled, norton anti-virus disabled. I am getting 100% cpu and nero freezes in the chapter and preview modes, I can't even get to the burning screen. Any other suggestions?
