Hi People, sorry if this has already been answered but my search has proved fruitless. I am ripping blu rays to the MKV container and reducing their size to around 6GB. I then store these files on a QNAP NAS which is connected to a Denon receiver which in turn plays to my TV. No major problems but sometimes I find the sound is not as good as it should be. Please could someone run through all the audio options in clone BD? When the blu ray has been read the main feature is selected and at the right hand side is a settings menu which shows a drop down with various audio channels ticked or not ticked. What bearing do these option have on the finished file? Which ones should be selected? If all are selected will the finished file have all those channels in the finished file? When you get to the window "Adjust Your Profile" you have the opportunity to choose the Audio Codec. Which one should I choose and why?
