audio distortion / crosstalk

We are using an HD2000 playing MPEG program stream 720p off a CF card. Our video looks great but we have split track audio and are getting noticeable noise which sounds like crosstalk from channel 1 on Channel 2.

We are using Apply Compressor to make the files with a pretty standard MPEG-2 template and there is no noise on the MAC using quicktime player.

Any advice on this?
