While it is good that Videotron will add those channels in HD, I still do not miss it. What I need and I have with Bell Fibe now that Videotron does not, and has no plan in the near future, are the timeshifters, CTV2 and TSN-Habs. I guess TSN-Habs is never since it is rather Bell-specific.
On the other hand, Videotron has FX Canada that I think Bell Fibe will not have anytime soon.
Another thing, what about video on demand? Bell Fibe has quite good VOD library in HD, I do not even have to record many of the shows as they are available there. That saves me quite a space on my PVR.
