The functions you describe should be repeating codes in that a given code is sent continuously until you release the button. On a short button press however, a given repeating code should be sent only once allowing for discrete control as you navigate the GUI. If on a short button press you are moving around more than one spot at a time there is a problem. My first suggestion would be to relearn the codes using the original remote, then testing each. In addition, try setting the duration for each to .10 seconds. I had some repeating codes which would repeat on a short button press myself. Setting the minimum IR duration for these codes to .10 seconds worked in my case.
