around here i had a similar issue with videotron, in the summer i would lose digital cable between noon and 4 pm every day, my analog signal would get full of static as well. Anyways, videotron would send one of thier sub contractors here either in the morning or evening, never when the problem was present. I gave up and spoke to a collegue whos brother is a supervisor at videotron, we put a booster on the line and all problems have disapeared. Videotron still insists there was no problem on the line, and everytime i call, insist i should switch to them for phone...
