I recently moved up to an HD tv from the 500 pounder plus the government issued box. Great picture and nice clean look for my living room, but, alas, there is no option to see what will be showing in the next few hours on the channel. I do not have cable or internet. With the dinosaur and the box, I could push EPG and see what's going to be showing for the next 6 to 8 hours. What am I doing wrong??
