Live type render movie issue

This goes out to you Live type gurus.😎 I have a 6 second animation with video. It renders in the timeline fine but when I "render movie" the finished product only shows about half of the total project. eg it stops half way through the entire clip. I've tried starting from scratch and it still does the same thing. Only half of it gets rendered. I have a full retail copy of Final Cut Studio 7. 😕 Thanks and I hope MikeyBouchereau is listening...he answered my last post quite well.
