Can I add a 721 and a 6000 together?

[rayvrwc]

I have a 6000, and watch OTA HD locals and now DiscoveryHD. If I go and buy a 721 for the regular stuff, can the 721 and 6000 be "chained" together, or do I have to run cables from the dish to each separately? Or, maybe I should wait another year for the 921, or JVC's TU9000 unit, which, by the way, any new news on when it's coming out?

Thanks,
Ray

Depending on the type of switching you use, and where you want to put them, your going to need a minimum of 3 cables from the dish to where your 6000 and 721 are going to be. They cannot be "chained" together or split.
