[FFmpeg-user] How to prevent timecode tracks in quicktime movies

I am converting a DNxHD 36 quicktime movie to h.264 quicktime movie using ffmpeg 1.1. I noticed that ffmpeg is adding a timecode track even though I haven't requested it, is there anyway to prevent this from happening. 

When I run the same command in version 0.8.4 I do not get the timecode track in the resulting movie. 

Here is the conversion command and the output of the conversion 

'ffmpeg' '-threads' '4' '-i' testgray.mov '-f' 'mov' '-vcodec' 'libx264' '-crf' '14' '-r' '24.0' '-s' '720x406' '-aspect' '1.77339901478' -preset slow -profile:v main -pix_fmt yuv420p '-acodec' 'libfaac' '-ab' '288k' testgrayh264.mov
