I have only had Videotron cable for 4 months. I have the pick and pay 20 channels package. When I tried to make a change thru the set top box after the first month, I could not. Contract issue error. Called Videotron and had the changes made. I mentioned to the tech that I was not able to make the changes myself. He mumbled something and said it should be okay from now on. Tried a month later and was able to add the west US channels, remove discovery HD and change a couple more with no issues. My next bill reflected all the changes accurately as well. So, yes it works for me. Never tried the website though, never knew you could.
