Most such streaming video problems are the result of a slow download speed. Dial-up won't do it.. And even the slow DSL speeds won't stream video well. Hopefully, you have 3.0 Mb download speed? If not, then you're best option for viewing video on the net is to increase your bandwidth which costs money.
Have you tested your internet speed? If not, click on the link below, which uses a Java speed test, (hopefully, you have Java installed) and use the link for a site nearest you.
Hope this helps.
I have a gateway laptop with tons of memory and space with a vista operating system. Any time I want to watch a video of something i.e. utube and the like....it goes for a second then buffers and takes forever to stop and show the video, then another second or two and it does it again. I can very rarely watch a video clip. What can be the problem? Like I said its not a memory issue or space as I have plenty of that so what can it be?
