I couldn't find the topic so I'll post it here. Qui-Gon Jinn and Obi-Wan DID know that Padme was Quuen Amidala in disguise. As if their knowing glances (esp. Qui-Gon's) and comments didn't give it away. Also, GL revealed this in the same commentary which he said Darth Sidious IS Emperor Palpatine (which anyone could've figuered out easily).
