DVR-S Recording Issues With MFD Crosshair AP

Hello,

I'm using the MFD Crosshair flight controller, which encodes the flight data (lat/lon/gps pos/speed/etc) for the MFD Antenna Tracker. This encoding is sent by the video channel.
The DVR-S is connected to the controller output for the VTX, so when the DVR starts recording, it takes a line of data at the bottom of the video, leaving the recording in black and white. I imagine this is happening because the DVR-S is recording in a different format than the controller (NTSC/PAL). Would it be possible to provide a firmware to solve this?
