First, this will be a board for the 103, not a 105. My mistake.
The Oppo103 actually has 2x HDMI input, not one. My mistake again.
You can check the specs/manual of the 103, to see what level of decoding the Oppo is capable of on the HDMI inputs. You can also post the question on this forum.
I would be very surprised if it could not decode whatever you feed it over HDMI (except for DSD probably), but also keep in mind that the only source of DTS HD or Dolby TruHD content are BR discs (as far as I know). So even if it cannot decode that for external HDM source, you would be needing that only on the discs you spin in the Oppo itself anyway. Even If there is an external device that plays DTS HD or Dolby TruHD content, you can let it do the decoding and feed the Oppo 103 LPCM.
