hi guys i'm currently having to use SDJ version 1.7.8 because if i use anything higher it makes videos i'm my mix emergency versions 2 & 3 lag and glitch freeze etc but the processor usage bar on my SDJ is less than half way. i've have spent all of today trying different versions updating optimizing etc etc but had not luck.. this is now a bigger problem as i've just purchased a Denon MCX8000 and can't use it until i get this issue fixed and i can use a higher SDJ version any ideas?? so i've already tried version 1.7.8 this works fine on The DDJ SZ, cdjs and alike 1.8.2 and above cause video issues on both the DDJ sz cdjs and my nex MCX8000 which has got the latest firmware My system is Mac book pro 2008 os version10.10.5 2.8gb dual core 8gb ram
