Every box on which you intended to be able to watch live TV needs a STB or digital adapter. The Home Media service is a STB to STB service -- so, yes, you need a STB on the other TV if you want to watch shows recorded on the Home Media DVR on that TV.
Note: If you record in HD, you need an HD STB on the remote TV in order to be able to watch that program. You can record shows in SD and watch them on other SD STB's, but you can't watch an HD program on an SD box via the Home Media DVR.
