That's been a point of contention for a long time. Robert Brown pointed out on his page that those areas are too obviously docking ports for them to be where the escape pods are, plus there are only two and in ANH the officer mentions *several* of the escape pods were jettisoned. But it looks like Brown won his battle, because now the docking rings are called docking rings.
Hey dnalor, have you ever tried using a soldering iron for blast marks? It leaves a nice burn mark without igniting the paper and you can "sculpt" the marking to look like the actual miniature.
