Have never been able to figure this out (and I'm not quite sure why!). Usually when I scan a bird, there are audio channels that scan in. How, using my Fortec Mercury II, do I go about listening to them?
That might work... but I'm using 1497 and/or 8193 for the video pid to do similar since my pansat's tv/radio function is screwed up somehow and it won't let me go in to radio except once and then back out before needing a factory reset to get it to work again. According to some posts in a certain thread in the WUT area, Zeros won't work on all receivers for video pid when you are trying to just get an audio channel in the video side... that thread also says, according to Mike Kohl,Put zeros in for the VPID and the audio number for the APID.
Normal Video PID for audio services should be 8191 on most consumer receivers.
You can also take any TV channel you are not using, or scan one in and edit the PIDs. Put zeros in for the VPID and the audio number for the APID.
