Right now I'm doing the same thing, going foundation-less from the start and as others have pointed out, space is usually the main culprit. Providing good guides along the interior top bars is also very important. When closing hive back, TIGHT, TIGHT, TIGHT frames are what I'm finding key. I watched the video and it looked like when you crack the hive you had some space between the suspect frames. The frames need to be put back tight, you're frame grip is preventing this from happening post manipulation. You should tighten the frames further, making them snug with your hive tool. There should be no little space AT ALL between the frame sidebars. If they have been propolized, take your hive tool and slide it along the sidebars. Always have an empty container along with you to scrape burr comb, cross comb and propolis into. I'm inspecting every 5 - 7 days and have minimized most of the "shinanigans" before they get going. Right now my hive is drawing about a frame to a frame and a half per inspection. We're between flows (mild dearth) and I' open feeding about 2 quarts 1:1 per inspection period. Actually starting to taper that back because the palm flow is starting to pick up. Also, try not to have two blanks side by side. That brood pattern looks good, if you have some room, an empty on the between two drawn frames on the edge of the brood nest might be a good idea. I've done it with some success, eggs immediately deposited in any available cells. Like the others have stated, always try to have drawn comb or at least foundation frames alongside the empty frames. One easy thing you could do is with the end frames on that hive is to exchange them. Take the outside drawn frame and swap it over the other outside position. Again, this is what I've been doing with some great results and minimal cross combing action. Good luck and keep it TIGHT.
