Can anyone please confirm the BS2 will or won't translate 455KHz down to 40KHz to control SKY from the BS2 IR output please?

I have a SKY HD box behind an Avant, bought the BS2 to be able to locate the SKY in another room and make the other room the downlink / uplink for RF. Haven't got an IR yet to control the BS2 and just started thinking the BS2 might not control the SKY using a Beo4 - i think the Avant needed a SKY control card - should this be interchangeable into the BS2?  I know i won't get HD through the BS2, i intend to connect directly to the local screen and for RF distribution via scart.
