Which software plays LPCM?

[mrg155]

Hi,

I'm looking to backup Blu-ray discs to hard-drive using the methods suggested on this forum and others. I have a Rotel AV receiver with HDMI 1.1 which is not capable of decoding TrueHD or DTS-MA but can do LPCM up to 24bit/192khz. My plan was to use eac3to/tsmuxer/tsremuxer to strip Blu-Ray discs to the main feature and convert the protected HD audio to LPCM. I will remux the LPCM and video back to a Blu-Ray .iso to use in My Movies/Vista Media Center/Arcsoft Total Media Theater for the '10 foot' GUI. Graphics card is a Gigabyte Radeon HD4850 which I understand can output 8 channel LPCM via HDMI. Will this setup work?

Specifically:
Can the HDMI output of the HD4850 carry full 8 channel 24bit/192khz LPCM audio (I realise the none or very few movies will have this 'maximal' audio)?
Will TMT3 (or the latest PDVD) output the full bit-depth/sample rate of a converted 'unprotected' LPCM soundtrack or will it still downsample to standard def 16-bit/48khz without a HDCP/PAP soundcard i.e. Xonar?
If I do need to get a Xonar to output HD LPCM can it send that to a HDMI 1.1 receiver/processor? i.e. can the Xonar HDAV1.3 convert TrueHD or DTS-MA to LPCM onboard and then output this via HDMI 1.1 to the Rotel for DA conversion? though I would prefer not to have to get a Xonar if it means I don't need to convert the audio to LPCM and only remux the main feature and HD audio then it's a reasonable alternative and I'd probably save disk space also.

Thanks for advice

Mods - would this post be better off on another forum?

Many thanks

Encode the audio the way you want and include both audio tracks(original and re-encoded) and try it.

You may run out of HDD space fairly quickly if you use the full size BD movie file and LPCM audio at probably ~15 - 30GB per file. I usually convert them to MKV, but I do use DTS audio. But I also output the PC audio over a coaxial connection to my surround sound amp and don't use HDMI audio as my projector doesn't have sound anyway.

I'll move this to the Blu-ray to Blu-ray Forum.

And welcome to our forums.
