I'm not following what you are refering to. If you go under the assumption that MRV is the gateway to having a whole home system (which seems to be a pretty good assumption from the directv receiver roadmap), then you simply can not do it without first implementing at least DLB. Oh, they may not call it that, or even advertise it as a feature. But if it looks like a duck and quacks like a duck. Earl was great at being overly pedantic. If Directv labels it as cheesy puffs then he'd say they have implemented cheesy puffs and not DLB. I'm more a hand grenade guy and thus will stick with that DLB functionality is a prereq to MRV as I understand MRV will work which I admit could be completely wrong.
