While some of the folks at the BBC might claim that HD would bring little improvement over SD offerings to their viewers and most wouldn't be able to tell the difference, my cat clearly can tell the difference.
I was watching Discovery HD's Toronto: Urban Wild on ExpressVu the other morning. My fourteen year old cat, seated beside me, caught a glimpse of the sequence with the ground squirrels. She immediately stood up and stared at the screen for a moment, then jumped over the coffee table landing in front of the set. She followed the action back and forth on the screen for a few seconds then stood on her hind legs taking swats at the screen. When the squirrel exited screen left she then jumped on the cabinet holding the set and went behind the set. Not finding the squirrel behind the set, she jumped up on top of the set before she gave up. I think my cat sees things a bit more clearly than the chaps at the BBC.
