When I canned the airwaves using a Hauppauge HVR-900H USB tuner, I found a channel called TV3 (AC-3).

From my testing so far it appears that the TV3 signal has AC-3 audio on all the time, usually 2.0 but 5.1 for those shows which are also in HD.

I am using a PCH to view the broadcasts. If I try to view TV1 say, there is no audio which I can understand given they are likely to be using AAC-HE LATM.

Just wondering why TV3 has chosen to broadcast AC-3 audio all the time (not that I am complaining!)

Its probably easier switching the 2.0 stream to 5.1 instead of turning it on and off.

Yes did see that. But it went OT in the last couple of pages!

Interestingly when I playback the captured files from TV3 on my PCH, it identifies the audio as DTS! But on my AVR the DD light comes on. For those HD shows (e.g. Bones last night) I get 5.1 audio I think so that's good.
