The question relates to what you are using 61.5. If you are going into a legacy SW64 switch to get some locals or CBS-EAST for Dish, then you will not have an extra line. I had one line going to Voom and another to a 5000 for HD recording, recently JILLED by Dish. So the answer relates to how the non-HD sets are configured. The 61.5 dish may still need to be tweaked slightly, even if you use one of your DLNB lines, as Voom is a little more fussy on pointing.
