It all depends on the film stock. A good, low grain Super8 film stock can deliver 720P without trouble if it is an anamorphic print. A good 16mm anamorphic print exceeds 1080P as long as it isn't on high speed stock, and both will have more colour than can be represented on DVD.

You would need to find a 'collectors print' that has only been shown a few dozen times or less. If it is on decent stock, then fading won't be much of an issue, but most of them are on Eastman stock and are nice and pink, or nice and green by now. Not to mention battered to hell.
