AC3, or Dolby Digital, is as its name says: is digital. I don't know
much about the sky box, I understand that there are several models. I
assume you are using the PVR150 to capture your video from the
composite out of the digibox. For digital audio, in general, you need
to connect the digital audio output of your digibox to your digital
audio input on your PC to receive and record the AC3 signal. To hear
the recording, you must have an AC3 decoder, which I assume you have
in your HiFi or stereo equipment that is hooked up to your 5 speakers.
I don't know what the 3 green/orange/black sockets are that you refer
to. Does the digibox have speaker output? Or are they 3 sockets from
some other device.
