Couple of real quick things after watching the video:
You aren't nearly close enough to the zipper with your left shoulder. Try putting that thing just a few inches away from the zipper.
Combine that with scooting down a little further. Can't really tell, but it looks like your feet are just into the footbox. Try having your feet touch the bottom of the footbox, then scoot back up an inch, or so.
Given your description of your canvas hammocks, I'm betting you aren't accustomed to a diagonal laying hammock. If you try to lay down the middle in a straight line, most gathered-end hammocks won't be comfortable. I can imagine how difficult it was for you to find the 'sweet spot' given your positioning. Honestly, you just need to position yourself for the way that hammock was built. The fabric will flatten out when you're in a good position and the nylon won't wrap-up around you because most of it will be stretched. Try it, you might accidentally like it.
By the way, continue with your 'smart' responses to people politely pointing out why they took offense and you will find yourself banned. That's not an opinion, just a fact.
