There aren't any tutorials I've seen (but then again I'm not all-knowing). What about playlists is causing you problems?
Playlists are pretty simple, really. All they do is play a group of timelines in the order you specify. The big deal about them is that they free you from the tedious work of setting up a bunch of overrides to accomplish the same thing (see my Encore 1.0 tutorial on setting up this kind of structure manually).
You may want to watch Daniel Brown's videos over at the Adobe Evangelists site to get a better grasp on overrides and other Encore topics. (Sheesh, this link gets used so much we should probably get it posted at the top of the forum.)
