Capturing LD digital tracks-is there a simple method?

I have a bunch of titles for which I would like to capture audio and re-sync with other sources, but with a mediocre sound card without a digital input is there any way to capture or is this even worthwhile without a dedicated capture chain?

Other than getting a new sound card you would be stuck with plugging the stereo outputs from the LD player to your inputs on your existing sound card. This can still sound excellent though.

If you're going to all the trouble to capture a lot of disks, why waste it by going through a weak sound card?  Get the cheapest card with digital input that has good drivers that don't drop or mangle samples, I'm not sure what that *is*, but it shouldn't be hard to find a used one for a reasonable price, especially used.

I'm currently doing this and running into trouble. Not going as smoothly as I hoped. I have captured 2 one-sided LDs without problems. I captured them twice and compared. They matched. Then I tried a 2 two-sided LDs and on each one, side one recorded fine, but side two on each had numerous samples which didn't match up. Mostly in the first 5-10 mins with a few later on. I cleaned the discs, but it made no difference. Both are concert LDs, one Japanese and the other USA.

My setup is:

Panasonic LX-600 optical output > optical to coaxial converter > Audiophile 2496 card in a G4 MDD running Tiger.

The laser lens has different tracking settings for each side, so (for your player, as one of mine) when you play side "A" you have no problems, while playing side "B" there are problems (quite surely tracking issue).

If you use the player only to capture, you should not use the autoreverse, but play each laserdisc side on side "A" - when finished to capture the first side, just eject the disc, manually reverse it, and play the other side on side "A" again.

The thing is, I get the same results whether I use auto-reverse or not. It's always side 1 of both discs that recorded perfectly and side 2 which has inconsistencies. I'm guessing there has to be a problem with the discs, but I've looked closely at them and see no damage to the surface or the foil. Or maybe my player isn't so good at properly reproducing the digital audio track. Either way, it's a shame as I basically bought this player just to capture digital audio tracks. However, my Pioneer player has the CLV smear and this Panny does not, so I'll be looking into re-transferring the video if I can get a better picture.
