Just wondering if anyone knew if there was another "more popular" stb, that may use similar ir codes?

I'm trying to get Xbox One, to control my Venton Unibox HD2 via the OnGuide (I'm part of the beta preview program). Unfortunately the Unibox is not in the database, and there is no way if "learning" codes a la Harmony remote way.

So was wondering if one of the more popular boxes may be in the database, that would control the Venton, even if it was just the channel selections.
