The more elegant solution is to ditch the DPP33, install a 1000.2 (110/119/129, Western Arc) or 1000.4 (61.5/72/77, Eastern Arc) dish and run the 118 into the LNB input on the 1000.x LNB. Then you can add up to 3 dual-tuner, DVR receivers with no multiswitch at all.
Since I don't watch HBO, don't subscribe to music, and my local HD stations are all on 61.5 and SD are on 72, I have a DPPlus on a D500 pan looking at 61.5/72, and that would leave me an input free for 110 or 118 Int'l channels. That requires MPEG-4 hardware, though, like a 211 or 722 receiver.
What's your local market? Do you subscribe to the music services or HBO? Maybe my rig would work for you, and the only gear you'd have to buy/lease is a current-gen receiver. If you upgrade to HD service though, the installer that swaps your box should be able to plant a 1000.x dish for free at the same time.
