Perhaps you'll end-up with the 34 still installed. You would only need the 44 if you will now have 4 sat. slots required for your new programming choice and/or if there was no way to run a second cable to the 622's location. If they can run the second cable and you will then have more than 4 tuners/DPP-compliant receivers they may just cascade another 34 into the system and run the second line to the 622. The 44s are still expensive and (I believe) in somewhat limited supply...
