Yes.
Not necessarily. Sometimes MediaInfo just doesn't display certain file properties. To be sure, you have to manually check the distance between neighbouring I-frames in your encodes.
You can do this with Avidemux, for example. Just press the UP arrow to go forward to the nearest I-frame. You can then count the number of frames between each I-frame (GOP size).
