Capturing video with multi-channel audio?

[h00z]

I am about to embark on a pretty hefty project and I need some advice...

I have a few movies on laser disk that have never been released on DVD. I would like to take those movies capture and edit them and master my own DVDs. Just for the experience, and so that I can finally ditch the laser disk player :)

I have the video capturing down, no problem, but my question is this... Some of the laser disks have multi-channel surround sound audio tracks (DD, THX) and I want to preserve those audio tracks when I convert to DVD. How do I do it? What is the best way to capture multi-channel audio? Once I get the audio, converting to DVD compliant AC3 is no problem. It's just getting the audio (intact) that I'm worried about.

The easiest and safest way I could think of is to use some sort of digital out(Coax or SPDIF/Out) from your LaserDisc to an SPDIF/In port on your sound card. If you have a pretty good sound card (ie.non-Creative) that has good multi-channel ports, you could resort to those as well. Personally, I prefer using ToSLink for the cleanest possible signal with very low RF interference.

The next problem might be as to which software application could capture the digital stream properly. Perhaps TotalRecorder or something of the likes? I suppose the easiest or best way would be to capture all 6 channel streams to separate WAV files and then use SoftEncode for AC3 compression. I have no experience in this field so I'll leave it for someone else.

Do let us know how this project turns out though:) BTW- Happy 30th;)

well how can he capture the sound from SPDIF or coxual to 6 seperated waves ?
Is there any software for this case ? Can cooledit pro do that ?

Good thoughts. I'll let you know how it goes. And yes, at 30, I am officially an old man :)

Don't feel bad man, I'm just one year behind you and have already noticed a few grey hairs.
