Was flipping between ShowtimeHD and regular showtime the other night, really just out of curiosity to see what is clipped out of the 16x9ish presentation to show it in 4x3 (ie, justifying to myself that this small fortune I've been spending really has value ;-) Was amazed to see that it was the HD signal that seemed to be cropped from the 4x3 signal! This was not the case on HBO, but clearly so on Showtime. The movie was definitely being broadcast in HD, but it was very clear that there was significantly more info top and bottom in the normal broadcast, and equal width of info on both channels. Anyone have any insight into this? Seems really strange, backwards from what I would expect. Thanks!
