Roamio Plus and Slingbox 350

I have Roamio HDMI to TV and also RGB Component from Roamio to Slingbox 350. There is one problem. Slingbox has an onscreen remote for Roamio Plus but it does not work for me. When I click on a button there is a pause in both audio and video as if the command was being sent, but there is no change in the channel. So I am stuck between two companies. Is the Roamio remote provided by slingbox sending the wrong codes, or is Roamio not receiving and processing the codes which slingbox sends.

Has anyone used this combination?

thanks
