I've not had the opportunity to play on either the SVM or DVJ before - however, if memory serves me correctly, I believe the audio and video channels can be separated so you could play the audio in through CDJs if you had them and play the visuals through the Video component input.
Specifically, check out page 10-11 of the SVM user manual: http://docs.pioneer.eu/Manuals/SVM_1000_DRB1422_manual/
