Playing around with my AzBox today I discovered that I can receive the NBC mux on AMC1 @ 103W on 12000. The receiver only scans in East, Central, and the feed channel. Is Universal Sports still available?
If it's not listed in lyngsat, we don't usually post about feeds in the open forum. I think you're speaking of S2 signals there too, so I have no idea. Perhaps somebody will send you a private message about it.
