Changing analog TV to digital flatscreen

I share RoyB's concern about the wall mounting. Not like a stick and brick, where there are solid studs to mount to. Not much you can do on an outside wall, an inside wall with a closet or such on the backside can have support added on the backside. In our case, both new LED TVs were mounted in place of older heavy tube types, and had plenty of shelf strength to support the new ones. With a little fitting, I actually have both sitting on their own base supporting the weight, and a bit of support added to the sides just to reduce vibration while moving. Like I said, post pictures, to let us see how it is going.
