What do you suggest as the BEST set up for the following system need?

I have a sony SAT-A2 using a RM-Y130 remote. It has RF and IR capabilities. I got this because I have the receiver in the living room and often watch tv in the bedroom. This remote allows me to switch channels in the bedroom on the receiver in the living room. The problem is that I want to get a new sat-receiver that has TIVO built in. If I get a normal directv receiver with TIVO, what system will provide me the same ability? Also, budget is NOT a concern, so suggest AWAY, oh maybe a budget option as well as a couple of dream options!

Thanks!
