Hi,

   every one .

   I am designing a board based on DM8168.

 I use the DVRRDK 01.08.00.15.

and I connected the IOUTD port derectly to the amplifier.

so my board only have the sd output.

and the video capture and display demos  in DVRRDK work fine

Now ,I want to display my GUI program showed in the monitor.

But In the dvr_rdk/dvrapp directory  , I found that the GUI QT program has only output for HDMI.

What can I do to output the SD display.

Shoul I modify some env in linux or In the GUI QT demo source code?

Thank all of you .
