Yes it is possible.
1. An audio cable goes between the lazer disk machine (RCA type, right?) and the sound card "line-in" (mini plug, right?) on the computer.
2. Capture the sound with some program (I use "audio cleaning lab")..or other/s.
3. Burn it to a cd.
I want to take the audio portion of a laserdisc concert to my pc (and then to a CD-R). Is that possible and what method do you recommend? I have XP pro with a c-media sound card (basic-no rca inputs).
