May be a dumb ? but I'm picking up a Panasonic BD55 player tomorrow.....when it needs an update does the disc just not work or will the machine let you know?

Yep, went out in the mad house on Friday and picked one up along with a few BluRay DVD's. Just got through watchin' Rambo First Blood. I haven't seen that movie in years and I was in awe at how good they got a 26 year old movie to look. Anyone got any suggestions on movies, new or old that have...
