Good questions. CD distortion include hard clipping from amplifying too much, whereas vacuum tubes and magnetic tape have soft saturation (still a distortion, just a different kind). Another distortion is that dynamic range compression is used, bringing up the volume of quiet parts of a song.
As for digital video jitter, I can think of MPEG compression artifacts, both spatial (e.g. DCT mosquito noise) and temporal (e.g. motion compensation errors, periodic keyframe refreshes).
