DirecTV Tivo & Netflix

[GCSeibert68115]

I've seen new Tivo boxes that come with the ability to connect to Netflix for instant viewing. I have two Hughes HDVR2 units for DirecTV that have been rebuilt/upgraded with InstantCake (I can't seem to figure out which version, though) and MFS Live 1.3b. Does anyone know if there are additional software upgrades I and purchase/install on these machines to let them connect to Netflix? Thanks!
