You have to choose which two channels you're gonna use for doubleplay, So it defaults to ch 201 until you choose, then afterwards you hit down arrow for flipping channels with buffers intact, never press ch button for changing or channel numbers just down arrow.
Edit: you can change to a different channel using numbers and still use Doubleplay but one previous channel you first chose cannot be changed.
Choose your first channel you want to watch 215 then choose your other channel 242 using the number keys button, that should activate Doubleplay and can press arrow down by the Select button. using any other button key press would just turn off Doubleplay and clear the buffers.How do you "Select" the two channels ?
If I am on 215 (NHL) change to 242 (USA) and then hit the DP button, it will go to 201, what am I doing wrong ?

BTW you have press down arrow twice when activating Doubleplay, which it will change to ch201 or ch 1, that's where you have to type in both the channel number you want then you hit down arrow button.
