Juki DNU-241H stitch problem

Turning the thread guide down could help a bit. Although I dont believe that is the real problem. 

I would take a look at the disc surfaces by removing them for an inspection.

Remove both tension discs and degrease them. Then take the flat side of each and polish them on a piece of 800 grit paper. Put it back together and readjust your tension. Take Floyd’s advice and rotate the last thread guide 90 degrees CW. 

Lastly, see if you can use less needle thread tension by loosening your bobbin tension first, then adjust top tension to balance. Thread that is old or is of low quality get dry and will crawl right out of the tension discs. Have fun!

Just my impression:

see the photo of the tensionunit

It looks like the tread is not between the two plates where the spring is but behind them.

i do not know this machine but to me it looks like it should be between them?

but its early in the morning here and i might be totally wrong...(if others say its threaded ok ignore this)

Just a picture of what you were describing at the end of your video. I think it's a good approach to keep your thread from popping out from between the tension discs.

Thanks Uwe for posting that picture to better clarify what I was describing. 

When first learning about sewing machines, threading them exactly as instructed is always hammered home. Eventually you learn more about what is going on with the machines and you figure out some tweaks that aren’t exactly taught or recommended but they work better in spite of that. 

Its an interesting process.
