Hi, I want to upgrade my HTPC so that I can play Bluray/HDDVD. I intend to change the motherboard and CPU and also increase the RAM. And of course I will upgrade to a Bluray/HDDVD. I would like to be able to hook the HTPC up to my Onkyo 875 via HDMI and have the Onk do the decoding. I know in order to achieve this I need the HTPC to output the audio as Bitstream via the HDMI socket to the Receiver. My questions are; 1.How do I go about it? and what's the most cost effective method available to me? 2. Will I be able to play Region A Blurays as well as Region B's?
