What I can see, from watching your video, is that you have a problem with your emulation/computer/frontend. Looks like you are losing 15khz sync when quitting back to either your frontend or desktop.
I know you posted about something earlier, but you need to explain your issues right here. You can insert a link to the old thread. Nobody will think to remember and look it up. I know language is an issue, but communication is more than language. You must step up, make an effort. Otherwise nobody else will.
Very briefly explain what you are trying to do, and why it is wrong.
Put keywords in the subject line, so people with right knowledge/skills can help.
Include all specifications especially about
- computer, hardware & software
- monitor
- connections, JPAC etc.
- anything else I haven't thought of
Good luck!
