First I do not know what board to choose. I have an Xfinity control. So all the recommendations below re: the silver comcast remote appear unusable for me. All I want to do is to click the correct buttons on the gray Xfinity control and/or the Sony control to start a dvd playing.
Thanks very much
Use the remote that came with your TV to select the correct input for your DVD player. Then use the remote that came with the DVD player to start the DVD. Do not use the Comcast remote.

On https://www.xfinity.com/support/remotes/, select either the "Silver with Red OK-Select Button" or the "Silver with Gray OK-Select Button" and then Continue. On the next page, select "DVD/Blu-ray Player" and use the drop-down to pick the brand, then Continue. In a perfect world, the next page would give you the code to enter for the Aux device to control your DVD player.
As previously suggested, don't expect much . . .
