Some Shout! Factory MST3K disks have quality issues where the image flickers and, after a lot of effort because my coordination sucks, I managed to get some pictures of the flickers. I'm posting these here for reference only. There may or may not be entertainment value in this!
These are from about 14:40 into "Money Talks," a short on the "Beast of Yucca Flats" DVD. This is probably where I mention that, while Vol 18 sucked as far as flickers go, Vol 19 had almost none at all. Can't wait to find out what Vol 20 is like.
