Yup, it's MPEG2 similar to DTV SD with odd GOP sizes, etc.
Local channel quality isn't entirely controlled by DTV, they're also limited to what your local channel feeds out. They do modify bandwidth quite a bit. I've got some streams which are 1G per edited hour and have seen the same show come in around 500M at a different time. Football season is the worst because they use so much for that package. Your locals might also be fed at 352 width, not 480.
dealdatabase is your best bet for good info on DTV innards.
