1. When you use the HDMI out on your HD-DVD player is the Audio stream at this point Lossless Hi-Res or is it downsampled in the player to 44K or 48K? So far the players I have tried output hi-def video but not audio?
James, I just picked up the Toshiba A35 which is their "top of the line" HD DVD player just released a few months ago. You have the choice on how HBR audio is output via HDMI from the manual:
Auto:
When an HDMI device is equipped with built in Dolby Digital, DTS, MPEG or linear PCM decoder is connected to this player. When you play a disc recorded in Dolby Digital Plus, Dolby TrueHD or DTS-HD, PCM is output (core only for DTS-HD).
When you play a disc recorded in Dolby Digital or DTS format, digital audio signal (bitstream audio) is output. If a connected HDMI device does not support Dolby Digital, DTS or MPEG, sound is converted into linear PCM to output. To output high bit rate audio, select Auto, then make another setting (Digital Direct Audio Mode: On/Off > for amplifiers equipped with Dolby Digital Plus, Dolby TrueHD or DTS-HD decoder)
PCM:
When an HDMI device which has multi channel input is connected to this player. When you play an HD DVD or DVD video disc recorded in multi channel in Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS or DTS-HD format, the sound is decoded and output in multi channel in linear PCM format
Downmixed PCM:
When a 2 ch digital stereo AV receiver or processor is connected to this player - we don't need to know about this
I thought I would get the HBR audio out from the analog 5.1 outputs and this not the case. From my understanding, the only way to get HBR is via an HDMI 1.3a into prepro / AVR that supports this.
2. I have had reports from reliable sources that the HDMI digital audio bitstream has noise issues?
Last week when I picked up the Toshiba A35 from my friends house, I heard his setup (the top of the line Onkyo Integra Pre Pro with the same model A35 HD DVD player) and I did not notice any noise. I wan't listening crictically though. We were watching parts of Transformers in HD DVD with the HBR audio.
