Welcome to the XBMC forums.
Have you tested this with the unmodified Quartz skin and with the default Confluence skin to see if this "skipping" behavior on the main menu also occurs? If it does, maybe it's your input device that is sending out multiple signals with a single keypress? Try a different input device to see if it makes any difference. Enable debug logging and, when it does this "skipping" behavior, examine the debug log (wiki) to see what signals are received by XBMC when you press the key/button.
