Did you solve your demodulator problem?
Yes I did, thanks! It was my sound card settings.
Here is the complete Laserdisc Surround to PC proses that I am using for my projects. So to have everything in this one post, I'm going to re-list a few things posted earlier in this thread.
The laserdisc player I use is :
Pioneer CLD-D704
This unit has RCA AC-3 RF and Optical Digital Out
Specs =http://www.laserdiscarchive.co.uk/laserdisc_archive/pioneer/pioneer_cld-d704/pioneer_cld-d704.htm
The AC-3 RF Demodulator is a
Kenwood DEM-9991d
The computer I use for my projects is a modified
HP media PC m7760n
The PCI card I use for video capture is
Hauppauge WinTV HVR-1600 NTSC/ATSC Combo
(using S-video input)
My sound card is a
Sound Blaster Audigy 2 ZS Platinum.
Now here is where my problem was.
The problem was with how I had (or did not have) my settings for my sound card configured in the Device Controls menu. I had to select the SPDIF in option, Set the card to use Bit Accurate Mode, And set the decoder to installed DTS/DD.
Seems that having a "Bit Accurate Mode" option for the sound card is essential to decoding 5.1 AC-3 RF signal from the RF demodulator.
Next, I will use Adobe Audition 3.0 to record the 5.1 mix straight off the laser. After that, I split each channel (Front Right, Front Left, Center, Sub, Rear Right, Rear Left) into six individual mono PCM wav files (one for each channel), and open the SurCode DVD-DTS encoder program.
The DTS encoder will re-combine the six mono files back into a new single 5.1 lossless DTS surround digital audio file. This lossless DTS surround mix file will then be re-synced to the film's video, and placed onto my preservation DVD for Bond fans to enjoy.
