What site are you talking about? YouTube? I’ve never seen this happen.

For long videos (3 minutes+) your computer saves some memory by forgetting about the beginning of the video that you have already seen. Therefore if you go back to watch the video again it could have to redownload what it forgot. But it shouldn’t be slower the second time. If anything it should be faster because the video will now be cached on the server and you don’t need to reestablish a connection.
