I have noticed that on PBS and ImagineAsia which have AC3 audio the APID reads 65535 (talking about KU digital). Is this how you can ID AC3? How about 4:2:2 and HD video? Any help on reading PIDS is appreciated.
 
65535 on the Coolsat is like 0 on other receivers. It mutes it. Otherwise you get loud “chirps” on it

The Pansat says the actual PID with AC3 after it like this

37 [AC3]


4:2:2 and HD really dont have any factors, excpet usually HD is above 20000 fro symbol rate (usually between 27000-30000)

Waveguides - do they need to be 'terminated'?
