I have a few DVDs with "Full Screen" on one side and "Wide Format" on the flip side. I wonder if they could do that with Blue-Ray on one side of the disk and standard DVD on the other side. With the price of the players coming down I think the biggest hindrance to many people switching to Blue-Ray is the cost of the disks. Many people (including myself) just don't want to pay more than they already are for a movie they only watch a few times. If they charged more for the disks I don't think they will have enough sales to justify stocking them in stores.
