Hi everyone. I just bought a dvd from Porcupine Tree at the market (6$) and i have a question about it. There is the DTS-HD 5.1 option avalaible but i do not have the blu-ray version ( i didn't knew a blu ray one was avalaible until i search a little over the net)

So look like my receiver dont want throw the dts-hd and only show DTS. Is there a diffrence in option from a dvd or the reciever i do not know ?
I dont care really about the image but sound...

Thanks
