Forum Post: DM8107 RDK Interlaced NTSC Field at a time scale issue

I am experiencing an issue with field at a time capture of NTSC video being passed through the scaler on the RDK.  The scaler seems to distort the 720x240 fields even though it is set up to scale 720x240->720x240.  I also have the scaling coefficients set to 1/1.

Here is the VLC output with the scaler in the path:

Here is the vlc output with the scaler removed:

This is the a frame from the captureLink:

This is a frame from after the passing through the scaler:

As you can see the scaler is really distorting the image even though no scaling is being done.  Is this do to the 720x240 frame size?  Should I be setting  up custom scaler coefficents to accomplish this?
