RF dongle for Roamio Remote?

Does anybody know if the RF dongle that comes with the Slide Pro remote for the Mini will work with the regular Roamio remote. I recently received a Roamio remote for my Mini as I personally did not want the slide remote. I emailed TiVo a few days ago to ask about buying the RF dongle for the remote, and they stated: "The dongle will only work the Slide Pro remote and not with a Roamio remote."



That doesn't make sense to me. If the dongle is a receiver for RF remotes, wouldn't it work with the standard Roamio remote since it has RF capability? Or am I wrong in this assumption?



Can somebody please let me know if this would actually work? And if it does, how can I get a dongle from TiVo?



Thanks for your help!
