How does one do this and not break the bank? I've got a big number of LDs (good grief I have nearly 150 LDs!) I'd like to capture the audio from and re-sync to DVD etc., and both a small budget and a small decent desktop to work with.

For video how well does this work?: http://www.amazon.com/Diamond-TVW750USB-ATI-Theater-Tuner/dp/B002UOUQ08/ref=pd_cp_e_1

Primarily I'm interested in the audio side for right now, but have no idea how to proceed as far as either external unit or new soundcard. (It'd would be nice to have something for doing my own needledrops later on.)
