Depending on your setup (119/110/129 or 119/110/61.5). Some of the NY sd locals are one 119 and are consus (these would be no problem, abc, nbc, cbs, fox CW and MyNetwork) others are on 110 (WNET, a pbs is consus, while the rest are on spot beam) so you would see the one pbs. the rest are independent, pbs and foreign language. The HD locals are consus and on 61.5. If 61.5 is not in your setup, you will not see these.

The Atlanta HD locals are also in MPEG4. What exactly are you trying to accomplish here?
