Eric has noticed that when he's recording U-verse on AT&T, his internet bandwidth drops dramatically. Leo says that's because U-verse DSL shares his internet with the TV. U-verse fiber optic is the other way. Leo says it's a crime that we can't get decent internet in the country that invented it all.
