Traktor Control Vinyl > Rekordbox DVS

hey guys,

has anyone running traktor control vinyls with rekordbox dvs? there are some infos about that, some ppl say it work, some ppl say it wont work. found this on reddit:

"Traktor vinyl are going to be double speed since the traktor control tone is double speed (2khz), you need to use rekordbox or serato vinyl."

and thats exact my problem. my rekordbox is playing the tracks at double speed and i dont know, if this is an control vinyl issue or not?! if i switch to internal playback, everything is fine. using a djm 750mk2 and everything is set to 48kz. 

any ideas?
