I was chatting with online support and they had me create a topic here as the link to the remote request was not working. The case number is 00908016.
I just got a slingbox M1 and connected it to my DVR box which is a motorola DCT6416 III through provider Cox Communications. When I went through the setup process, I selected my correct provider along with the model of box. The virtual remote seems to all work correctly except for the Yellow Triangle A button. This is a critical button as it is used to confirm deleting or recording of shows. Without it working I cannot set anything to record or delete. Also of note, the current virtual remote says comcast at the top.
