Streaming generally means you're playing it off the internet without downloading it first. Is that what you meant? If so, that depends on your internet connection more than your computer. If that's not what you meant, then I don't know exactly what would affect video playback speed, but 640MB of RAM seems on the low side to me. What video card do you have? -- Rich
