Sony BDP-S5100 Streaming Activities

Has anyone programmed their Roomie for an “Activity” that is streaming a service (other than Netflix) on the Sony BDP-S5100?

The BDP-S5100 (BluRay Player) remote has a button dedicated to NETFLIX, so that’s easy. For Vudu, Amazon, YouTube, one has to go HOME, then scroll. This is problematic because HOME does not always land the cursor in the same spot.

Are their discrete codes for Amazon, Vudu, etc?
