I have an old compaq presario 6350us desktop with wxp and a 2.4 ghz processor and it has a choppy video when streaming from the internet, either videos from youtube or tv shows from websites like cbs.com. I was just wondering the processor is not enough to stream from the internet. It plays videos and dvds all right. It just won't stream from the internet in any way. It has an nvidia 6400gs pci graphics card and 1gb ram.
