After years of subscribing to TV Guide, they changed to their new format which I hated and ended up cancelling. Now that I have D* it wouldn't have been much good anyway. Even with TV Guide's weekly guide, there would occasionally be shows that changed last minute and the guide would be wrong.
I recently went to tvguide.com to look up listings for D* and I love it! You can see at a glance new shows and simply scroll down the entire list of channels fast compared to any of the equipment online guides. I think this is how I'll be seeing what's on ahead of time from now on.
