I recently had a problem with a Samsung TS160 receiver which DTV replaced with a H21-700. This left me without local HD channels since DTV doesn't provide them and the tv in that room doesn't have a HD tuner in it. I called DTV and they provided a AM21 tuner to go with the H21, unluckily at no charge but this leaves me still without HD since the receiver and AM21 aren't compatibile. I've been lucking in the CE forum and see that the latest CE release includes the feature to make these units work together. So here's my question: Since the power cord on the AM21 isn't a standard two prong cord, how do you power the AM21? I assume that the AM21 will plug into the back of a HR unit but there isn't any AC power out on the H21. Any ideas?
