I just remembered Star Trek: The Motion Picture - not only was it badly re-edited for the DVD, but at the insistence of the late Robert Wise, CGI was added to show V'Ger coming out of the cloud and to show a big granite bridge forming in front of the Enterprise for Kirk and the gang to walk across. It was terrible. I mean, the film itself is okay but these changes suck. Plus the pacing now feels really jumpy and erratic.
