Teleconverters tend to work better with some focal lengths and some lenses than others. I suspect the Canon ones are optimised for use with long lenses, and that the 200mm lens is ill matched. That is consistent with the fantastic results Andy (and others) get with a TC and a 600mm lens. Nikon even had two teleconverters, one for long lenses, and the other for not so long lenses.
