I guess all STB's are different, but, all 3 of mine show the channel with these PIDS as ABSCBN TEST 2. Another thing I noticed is that when I scan this TP with TSReader, this channel shows up on the left hand side, but, in the center where it shows the active PIDS and how much bandwidth they are using, this channels does not show up. Seems like they are sending info on where this channel should be, but, it's does not seem like it's actually in the stream. Even scrambled channels show up in the stream, they show as red, but, they are using bandwidth of the TP. This channel isn't there though it shows up in a scan.
How did you make it come up as 2STV on yours?
