I tried a similar thing with a pinhole camera setup to capture the full screen on a B/W paper negative (but you could use panchro and color film, of course.) I used a pinhole sized about the same as the pixel size of the video screen, since you don't really need any more sharpness than what you're limited to by the video pixels themselves; plus, larger pinholes mean shorter exposure times.
During last year's US presidential election I recorded several hours of the election night coverage, then reviewed them and freeze-framed the appropriate footage where I like the compositions. Some of the most interesting freeze-frame images were during dissolves from one scene to another, for instance the face of an adoring fan dissolving to candidate Obama's face, etc. Lots of interesting dichotomies to play with, subject matter wise.
Once the appropriate freeze-framed image is selected, you can then set up the pinhole camera and capture it on film.
PS: You can calculate with good accuracy the correct distance from the video screen to the pinhole on the camera to get the video image to nearly fill the film's frame, by using the following ratios. Assuming your video aspect ratio isn't the same as the film's, just use the figures for the video screen's width and the film's longest dimension. You supply three of the following values, and solve for the fourth. Most likely you already know your video screen's width, and the film size you wish to use, so you're left to decide on the camera's focal length and/or the required distance from the screen to the pinhole.
(width of video screen)/(distance from video screen to pinhole) = (width of film)/(focal length of pinhole camera)
