VDJ waveform

hi Pulse

I'm happy user DDJ 1000 for a month. I'm a VDJ and my problem is with the waveform when I play mp3 and mp4. When I play mp3 song and turn on the Video Function then the waveforms start to jiggle. When I turn off the mp3 the waveform starts flowing very steadily. Of course it's the same with mp4. I am using an AMD 4600H processor. Thank you for your help.
