Double Play

So my Double Play feature is not working properly. I'll try using the double play by hitting down arrow twice and tuning to both programs I want but when I try to toggle between it will go to a totally different ch I was never watching (in this instance 201 Sport Schedule) and the ch I pressed the down button twice on. No matter what I do I can't get the 2nd tuner to go to the channel I want my buffer to record.

Both my tuners work just fine. Can record 1 show watch another all that great stuff just double play isn't working. Am I doing something wrong?
