I too have been waiting for Videotron to activate the DVI port, but the last email correspondence I had with them left me with some hope of impending implementation.
"Regarding the DVI port, we don't have an activation date yet. We hope to be able to do it this summer."
Summer is so short in Canada that it can't be long now! Right? Right??? Anyway, it's kind of frustrating when the cable company across the river has it activated and I'm left using... ugh... component! :P
