HDMI and Audio

Feel Like A N00b



Ok picked up an HDMI cable from work today.


I have a question.


i Have SA Explorer 8300HD DVR that Comcast provided me with.


I have the opti out running into the AV receiver.



And of Course HDMI for the video.


My question is this


In the Cable box settings under HDMI it gives three choices for audio



Dolby Digital


Which of these do I want it set on and what are the differences?


Or is it irrelevant because of the opti cable?
