I didn't mention, I also have a MacBook (not Pro) running 10.5.8. This is the one we use all the time, and we can get Netflix, no problem. The PB is bigger, a 15" screen, so we wanted to use that for streaming. But alas, not a good idea.
My iTunes is 10.1.2. Will I be able to stream Netflix on an iPad2? or 1?
