Like a lot of you guys I have the 2010 MBP and I'm looking for a MDP to HDMI that supports audio. I don't know much about audio. My question is, what is the difference between A and B.. A] Supports uncompressed audio such as LPCM. B] Support compressed audio such as DTS Digital, Dolby Digital (including DTS-HD and Dolby True HD) Some adapters support A and B and some only A. I want to be able to watch DVD's/DVDrips and some youtube videos. What difference will it make if I get one that only supports uncompressed audio?
