timecode cd vs MIDI

hi all,
I just got my hands on a Denon dns 1200. The guys at their forum say that transferring the cd timecode to the USB will give the best/most reliable timecode performance. Can the mixvibes cd be copied and transferred?
2nd is there a benefit in using MIDI instead of timecode in terms of latency and performance? is scratch function of jog wheels effective with MIDI learn?
