Why does my internet connection stop when I'm uploading video?

Vance says that when uploading data, it completely hogs his bandwidth. Leo says that's usually true. If he saturates the upstream bandwidth with videos, the connection can't do any other internet activity as a result. Can he split the bandwidth to prevent that interruption? Leo says that's why bittorrent works better. There really isn't a way to do it unless his router supports it. Leo says it may be more practical to set the videos to upload as he gets ready to go to bed and let it run through the night.
