I just finished an HD television program, and since we were a documentary program using footage supplied by consumers at certain points, I found that mpeg video clips, dv video clips, and large still photos were typically the most suspect pieces. If you have a gigantic still, try to shrink the photo to the minimum size neccessary to fill the frame. If you have an mpeg or dv footage mixed in there, I would take it into it’s own project, and export it out to an I frame format. In my case, since we were mastering at 720, and upconverting to 1080, I would render those pieces out to and 1280×720 pro res movie, and that seemed to take care of those issues. Hope that helps.
