Ok I've run out and spent a bunch of money. Saw a nice 650W home theatre receiver/decoder for only $169CAD, wasnt shopping for it, but at that kind of price what the hell. I have the Epson Powerlite S1+ projector for a 12 foot diagonal screen and the old DVD/Surround combo was literally cooking (had to go in there and splice in a new Pentium II fan because the old one melted. peice of junk) and was no match for the screen size.

That led me to another purchase - Creative Audigy Sound Blaster 4. The thing has a digital SPDIF or S/PDIF out which means I can plug it straight through to the receiver and have it decode. The receiver can decode anything, Sony ATRAC to MPEG-2 and of course, the beloved Dolby Digital and DTS 96.

There was a bit of a learning curve to get around the misleading wives' tales (no disrespect to wives) about how the coax does 5.1 or 7.1 no problem. Ok fine I use Dolby Pro Logic II to rerender any non compressed source (Dolby Digital or DTS) and the receiver automatically flops back to the digital multichannel mode when the signal is detected.

Got it all working, tried out the stuff, works. Only one teeny little problem.

In Cyberlink's player, i've set it for SPDIF pass through (dont decode, let the receiver do that). Works like a hot damn. In Winamp, I play an AAC or DTS file and it passes through, works like a hot damn. Of course, soundblasters overly glitzy mouse driven player that comes with the card, works like a hot damn.

However in GBPVRs DVD player (which to my understanding is simply the Cyberlink), I cant set it to SPDIF. It only goes to PCM Linear mode. Kind of a bummer.

I have the media centre hooked up to the FM, the Cable, the DVD, the TV, the Projector, use the remote that came with the ATI Theatre 550 Pro loving GBPVR, I dumped the one that came with it, Cyberlink PowerCinema, that one just sucks (ahem.. PAY for the EPG? forget that).

Creative's player even uses the Cyberlink Audio Decoder to decode audio, and it offers the SPDIF option. Can I set this in GBPVR? I've looked through the config tool and even through the config.xml file, I cant find anything reasonable that would allow me to set such a thing.

Any idea how to set GBPVR's setting for the audio decoder to SPDIF?

Its not a GB-PVR setting, so not the sort of thing you'd find in config.xml. This is really an feature of the audio decoder and audio renderers you're using.

Getting this going has been discussed a few times in the past, so do a forum search and I'm sure you'll find a few threads on the subject.

I've done keyword searches for

S/PDIF
SPDIF
Pass Through
Dolby Digital
DTS

Havent come up with any results. Maybe the search is broken

Finally look up stuff on ac3filter which is what I currently use (you'll see I'm in most of those above threads about cyberlink decoders).

umm,can't you specify the dvd audio decoder separately in config? Big Grin
try the dscaler audio decoder or MPV audio decoder [mplayerclassic] and let me know if they work for you...they both have spdif passthru settable..even tho gbpvr doesn't let you get to those settings, they are there..

Sub, really wish the filter properties was available for the dvd codecs,as well as audio on both dvd and playback screens, as most of these filters have settings nowadays that can be quite helpful..

to set the filters manually, get mediaplayerclassic and and use it's abilities to change the defaults, or graphedit and insert the filter and adjust..not sure if it will save them as defaults or not tho..the video decoder works that way tho..
[set it in another app and it becomes universal]

there's also a few ac3 specific filters out there that can do spdif, check out the mplayerc site for some nice ones...

anybody know how gbpvr handles multiple formats on one dvd? say mp2 audio and ac3 audio choices, will it default to mp2? or ac3? or just the default audio track of dvd?

check those off and see what ya get..Smile
[audio decoder is installed with video decoder package]

MPA decoder from MPC also has same capabilities..

I cant find the build your using. (5008)

Most recent version on their site is 4373. Dscaler 5 is listed as pre-alpha on their site.

Where do I either find the 5008 or find the setting in 4373? I have hunted through their settings and advanced settings and even the help files and there is no mention of SPDIF

Ok I found it. But cant find the settings described for the life of me. It mentions them in the help files, I even scanned the registry. The codec is there and available, but I cannot find the settings. ? Any ideas?
