Playing "side-a + side-b" dvds

Hi

This is a question for USA people who know about Region 1 DVDs that have 2 sides.

I just got a DVD from the USA via Fishpond.

Mac DVD players can read all regions. Being in Australia we are in Region 4. USA is Region 1.

So on this USA disc from VIZMedia. It has two stickers on it. The outer sticker states "Side A". And on the inner sticker is "Side B". So to access "Side B" does that mean I flip the disc?

Thanks very muchly if you can help!!!
