I have been recording mp3’s with VDJ at 192 bit rate and never had any problems, no glitches, no static, no nothing. It has worked perfectly fine with me. You have the option to record as WAV as well, which is a larger file with much more quality, but mp3’s at 192 is also pretty darn good. I have used traktor before, but have never recorded with it, but as as soon as I get it set up correctly with my new set up, I will try to record with it as well.
