I use a HDMI cable for both my PS3 and my HD-DVD player. Before I bought my Anthem AVM 50 I had to use the analog inputs on my AVM 20. You dont need HDMI 1.3 (1.1 will work) to get the new sound formats, the player decodes the sound and then sends it out to the processor or receiver in PCM. At this point, there isnt a processor or receiver that will decode the new sound formats. ONLY the player is capable of doing it. If you use the standard Toslink or Dig Coax cable you WILL NOT be able to receive the full bit rate the new sound formats (Dolby TruHD, 5.1 PCM, or DTS-MA)are capable of.
Bottom line, if you want full resolution, use either HDMI or you analog(multichannel)connections.
