So I'm fairly new to the world of HD, as in I just bought my first HD TV a few days ago. I'm wondering if it's normal, or what I'm doing wrong, but some channels/shows are full screen on HD, but most aren't, they either have black bars on the sides, or top and bottom, or both. So a lot of times there is just a smaller image in the middle of my TV, which leaves me wondering why I purchased a 50" TV if I can't watch 50" of TV. I've got a Bell 9241 HD PVR, connected to my TV with HDMI, and have some decent HD programming but it's looking like most stuff is "fake" HD to me. For those who know Bell, the HDTV setup in the receivers menu is set to 1080i/16x9, and my TV's ratio is set to 16x9, but as I said, most stuff I need to stretch/zoom/etc to fill the screen, then it just makes everything look squished and out of place. I would really appreciate any help getting it sorted if I'm doing something wrong or have some settings not set correctly.
