Bitstream problem on INtel DH57JG via HDMI

[cjbrown80]

Hey gang,
As I've had no luck with this issue on the AVS forums official Intel DH57JG thread, I thought I'd see if anyone here can help (keeping my fingers crossed while typing with one hand). I recently built a media center pc to use with an InfiniTV tuner card (which is awesome, btw) and all that is working fine, but the Intel DH57JG mobo claims to be able to bitstream DD, DD+, DD TrueHD, DTS and DTS-MA via both it's optical and hdmi ports. The a/v receiver is an HK AVR3600 which is definitely capable of receiving every type of source audio (DD, DTS, LPCM, you name it) and my PS3 regularly bitstreams all of these formats from BluRays perfectly. The mcpc on the other hand, as of right now, successfully bitstreams Dolby from live or recorded programming that uses it(via WMC). When I fire up MPC-HC (tried both 32 and 64 bit versions) using ffdshow (build 3529, 32 or 64 bit), and try to play back a .m2ts file (backed up from a bluray), the bitstreaming does not work. What the AV receiver gets is a decoded PCM stream. I've had varied results with what type of pcm stream, at one point it did sound like it was 5.1 discrete channels, and at other points it just sounded like it was stereo, but the AVR only ever displayed PCM, whereas it will display Dolby or DTS or whatever specific codec it's receiving if it's a proper bitstream. I did try Arcsoft TMT3, which is cool (especially how it incorporates into WMC), but it yields the same non-bitstreaming results with or without ffdshow installed. Some other folks on AVSforum that are using the same mobo (Intel DH57JG) claim to have perfect bitstreaming from MPC-HC using ffdshow, but both of those guys are using Onkyo receivers (not that it matters). As I built this rig to 1)watch and record HDTV (working perfectly, Ceton rules! ) and 2) playback .m2ts files from my bluray library (NOT working perfectly), I feel like it is only fulfilling half of it's intended purpose, doh!
If anyone has any suggestions as to what specific versions of software and codecs I need to be using, or if there's a specific step of the ffdshow install that I'm not doing correctly (you know that's a possibility with that complex setup process) please let me know. I've tried everything.... I'm at the end of my rope with this, and I feel defeated... blaaah....

Thank you extremely, sincerely, ridiculously much, in advance,
Chris
