The problem is most likely you are using layers.  Say you have the base layer and one other.  If most of your camera movements were mad on the Base layer and then you switched to the other layer and made a camera movement, it is going to override the lower levels movements and you get the camera jumping all over the place.  Best thing in the world is to ignore the layers feature and only work on the base layer. Highly unlikely this will ever be fixed. 

I have found that the order in which I add animations is crucial to the stability of the layers. For years I would just use the base, and make all the tedious correction after adding new keyframing, but I got tired of the tedium, and started using new layers for each new animation. This seemed to work better; less having to go back and adjust each frame after adding key frames. But this recent attempt to use the UI dots pretty much tossed everything I thought I knew about it out the window. 
Thanks for the input, It's all helpful.
