I have used PS3 for three years now, and like you all have found it a powerful tool. I would like to offer a few ideas...If you already know this, I apologize, if not, feel free to add:
First, I LIKE the fact that video is not an option. As a former English teacher, I always want kids to focus on the STORY, and use superior images to support. As you can tell, I use PS3 primarily for Digital Storytelling, and by that I mean personal narratives that focus on individual, incidents (Thanks to Joe Lambert)
Do you ever have files corrupt on you right before rendering? If so, it is usually because:
1. Names of images have spaces or symbols in them. instead of "big dog" use "big_dog"
2. One of the more fancy fonts is used on a black screen. Solution: Make sure the blank slide is a JPEG file, AND you use simple fonts, OR place text on a washed-out image for effect.
Although seemingly simple, some rather sophisticated "Ken Burns" effects can be created with some practice in the "Customize Motion" Screen. To illustrate, I have attached a couple Mini Tutorials. For more and some other helpful tools, please visit my DST web page:

Let me hear from you all!
I am looking forward to hearing from other PS3 users!
