You might look at Carrara4 Studio Pro. It can import Poser 5 files using their Transposer plug in. It also handles sound files. I don't know about sync. yet. You also need to remember to do short scenes that can be rendered and then put together in a non-linear video editing ap. With a good video editing program you can add sound and titles and additional video files as needed. I use Sony Vegas 5 and love it. I do all of my audio work in Adobe Audition.
