There was a noticable problem with the video transfer of this episode when the original Volume 14 came out back in 2000, and according to reports and the HTF reviewer, it has not been corrected for the new Season One boxed set. The video problem is a vertical "jittering" of the image that last for minutes.

The video transfer should be properly done. If there is no chance of it being fixed for DVD, then it needs to be corrected before the episode is released on future video formats with this defect. "The City on the Edge of Forever" is perhaps Star Trek's finest hour, and it should have a video transfer on par with the other episodes.
