So I've finally gotten my new computer up and running reasonably well. It's got a DVD player, which means that I can take screencaps directly from any DVDs I've got, at least if I can figure out what I'm doing. I didn't think to save the image under a name that I could easily remember it.
As for the capture above, that's Alec Guinness in The Captain's Paradise. Some months back I ordered a five-movie set of Guinness' work, mostly because I wanted The Lavender Hill Mob; this one is the one movie in the set I hadn't seen before. So I popped it into the DVD player to see if it would play (it did) and then fast forwarded to an arbitrary point in the movie to see if taking vidcaps would work (it looks like it does).
