622 Install tomorrow. Any Suggestions?????

[dznylvr]

I am having the 622 installed tomorrow.

I currently have an 811, 510, 501, 311 hooked to 2 Dish 500's and a DP34, and I have an OTA.

I am having the 622 replace the 811 and want to keep the 510 on the same TV as the 622.

Right now I have one feed for the 811 and one for the 510.

What do I need to ask for to keep the 510 and split the second signal to the 622?

Thanks you for the help.
