I have a Motorola DR922.. and it works fine all set up with my satilites.. I am trying to find T4 for pbs 600 601 602... I see them listed on the bird.. but I do a scan with the dish from a count of 4000 to 3500.. but not a thing. I have been watching c band for at least 15 years... andI have set up 2 922 receivers... but right now I am stuck..
Oh, I misunderstood what you were trying to do, didn't realize you were working with a 922. 4DTV is one of the (many!) things I have absolutely no knowledge of, hopefully someone else can help you get it figured out.
