Ok, I read and re-read this note on the TiVo forum. Looks like I'd need to install a multiswitch at the dish and expand the number of cables I can have running from the dish. That's not my goal. My goal is to NOT run another cable. I already am feeding 4 receivers from the dish and I can't run another to my place...

That's why I am looking into an AB switch box...
