I like to use my Compaq Presario 2100 to watch streaming vids, but recently it hasn't been working very well. It'll buffer, play for a second, stop, buffer, play for a second, stop, buffer, play for a second, stop...and so on...sometimes playing audio while the video isn't even moving. I don't know why it does this cuz it used to work great. I have cable internet with a wireless router (connects at 54 Mbps), so I know it's not a matter of bandwidth. What can I do to make it work better?
