DVD DD/DTS Playback via SPDIF with InterVideo Audio Decoder (iviaudio.ax)

[beaverm]

After searching the internet and not really finding anything at all for my issue. I discovered a fix for it myself:

The Option for S/PDIF was greyed out in Windows Media Player 10's DVD Selection for iviaudio.ax.

What I had to do to get it "not greyed out" was simply insert a DVD and go back into the options, and magically it was no longer greyed, however it sill would not work in GBPVR (however Media Player was now working)

upon trolling through my registry I stumbled upon:

HKEY_USERS\{User String}\Software\InterVideo\Common\AudioDec\GBPVR
and
HKEY_CURRENT_USER\Software\InterVideo\Common\AudioDec\GBPVR

Which were both blank, no entries what-so-ever.

There was also:
HKEY_USERS\{User String}\Software\InterVideo\Common\AudioDec\wmplayer
and
HKEY_CURRENT_USER\Software\InterVideo\Common\AudioDec\wmplayer

which had the following entries:

AUDIO=6 (decimal) (type = DWORD)
AUDIOCHAN=7 (decimal) (type = DWORD)

Now the option worked fine in Windows Media Player so I duplicated these entries in GBPVR (in both locations to be safe) and started GBPVR up and now Dolby Digital works through the InterVideo Audio Decoder (Using Direct Sound Default)

For reference my system is:

AMD 2600+
1 GB RAM
2x PVR250
Creative Labs Sound Blaster Audigy 2 ZS
ATI AIW9600

Windows XP SP1 w/ WMP 10

This was a clean install, so there wasn't anything on the machine when I started.

I'll get around tomorrow to testing DTS on it (it's late and i'm tired).

This may have been posted before, but I couldn't find it, and figured this may help someone else out in the future.
