Re: Yamaha RX-V3800 and Toshiba HD-XA2
A few things here...
First the Toshiba HD-XA2 currently does not output Dolby TrueHD as bitstream for your receiver to decode. It only has an internal decoding processor for TrueHD and DD+. Theoretically, the HD-XA2 is HDMI 1.3 and should be compatible with carrying the bitstream audio, however, only time will tell if a firmware update will add this functionality. The HD-XA2 is also not capable of DTS Master HD Audio. It is however capable of extracting the "core" DTS audio from the DTS HD HR and DTS Master HD tracks (essentially just the standard DTS bitrate you would find on regular DVDs).
Second, DD+, TrueHD, DTS HD HR and DTS Master Audio can only be output via HDMI in either PCM or Bitstream formats (in the case of the HD-XA2 just internally decoded PCM). Toslink and Digital Coaxial does not have the bandwidth capable of carrying PCM or bitstream of the above mentioned audio formats.
Currently the Toshiba HD-A35 is the only HD DVD player to output TrueHD and DTS Master HD audio tracks via bitstream to a receiver capable of decoding these streams.
If your your receiver is displaying DD when using HDMI, go into the player's setup and change HDMI audio output to PCM. If you want toslink also connected, then I would probably leave that connection set as Bitstream and use it as a backup for normal DD tracks.
Basically, with the HD-XA2, your best option is to let the player internally decode all audio formats to PCM and output via HDMI to your receiver with is capable of receiving Multi-Channel PCM audio via HDMI.
Toshiba dropped the Silicon Optix HQV Reoon video chip in the HD-A35. The HD-A35 now uses the superior Anchor Bay VRS Technology. This is the same company that creates the outstanding video processors like the DVDO VP50 PRO.
Hope this helps.
