Usually, software is distributed under license, and people do not acquire "a copy of the software", they acquire a license to use the software. A video of a person using the software (no matter what they are doing with it) is not a violation of copyright, so you can't use DMCA take-down to get the video taken down. If the license terms explicit stated that a person cannot make a video of themselves using the software, then you could have a basis for suing them for their original copying of the software (installing software requires permission, thus compliance with license conditions). However, if there is no condition in the license that forbids a person taking videos of himself using the software (or something to that effect), then you have no control of videos that they might post that are "about" the software. There is, in particular, no assumed control
If the action being recorded is of a person violating a license term (example: "Here's how to thwart copy protection... there, now I have two copies"), the video is useful evidence of the violation, but making such a video is not itself against the law. The notion of "display rights" is connected with public performances of works of art, so for example if you legally buy a movie, you still can't show it in public without permission; you can't legally read a poem to an audience, without permission. Software might be involved in getting a work of art "out there" (mapping it to a display device), but such protection involves publicly displaying the actually-protected original work (the thing that the rights-holder created). For example, a word-processing program might (gratuitously) display a drawing when it is opened, and the drawing could be subject to "public performance" type protections, even though the operation of a word processor would not itself be so protected. Ordinarily, all that you can publicly display about software itself (not a think embedded in the software) is an instance of a person using it, and all that is protected about software is the computer code.
