Toby, I've gotten rendering crashes if I have a gap between two adjacent clips on the timeline. To stop the gaps from happening, I will go to the end of a particular segment, zoom in as far as I can go, and make sure that the audio and video tracks end at the exact same time.
Another way of saying this is that the end of one clip and the start of the next should line up perfectly on the timeline. If they don't end at the exact same time, I clip off a bit of whatever track is dangling by using the mark in/mark out indicators and doing a "cut". I can then be assured that when I paste a new segment to the end of this recently snipped one that the segments will align perfectly. Once the segments are aligned, I then apply the transition and feel secure that the video will render properly. scott ps - it also helps if you have Settings->"Align cursor on frames" option selected so that you always have measurable reference points to do your cut and pastes.
