Recording MachineDrum SPS1UW live

Anyone encounter what seems like an internal timing issue? Here is the set up that I used and what happened:

MD SPS1UW with 2 audio cables out main left and right directly to stand alone CDR burner. Headphones into headphone socket. 1 pattern at a set BPM every 96 measures or so there seems to be a lag or change in velocity on the kick drum. Also when fading the volume in or out on other channels with the VOL control the control itself seems to become hyper-responsive; the slightest value change seems to make a noticeable, drastic, undesired effect.

Does anyone know of any other recording labels buying songs?
