Nancy,
Great perspective and suggestions. As a back-up plan, I usually avoid video's just because they are static, allow for no engagement, and students can tune out. I have some 2-3 minute video's or DVD's that are pertinent to the some lessons, and these are good because they're short, to the point, and are specific to the lesson. The other change up's you mentioned are great, add variety, and help keep student attention.
