This ARTICLE talks about some ways to do A-D Capture.
Fairly recently, someone mentioned that they had picked up a busted miniDV tape camera on eBay for ~US$40. The tape transport was busted, but the pass-through worked fine. Maybe an idea there.
Old forum discussion, message now gone, but here's the summary
Matt with Grass Valley Canopus in their tech support department stated that the model 110 will suffice for most hobbyist. If a person has a lot of tapes that were played often the tape stretches and the magnetic coding diminishes. If your goal is to encode tapes in good shape buy the 110, if you will be encoding old tapes of poor quality buy the model 300
Both the 110 and 300 are two way devices so you may output back to tape... if you don't need that, look at the model 55

thanks for the info.... just not sure why if i record live to capture with no tape and for testing, just shake the cam around like its a crazy cat... it looks fine... but if i do the same thing on tape and capture off the tape, its just going crazy. tape is good. and the image looks fine on TV. but for some reason, it doesnt wanna be digitized. skips frames, frames off screen, lines all over, until the camera is stationary in hand again. somewhat irritating. i tried dubbing to VHS and then over the capture card... the bahaviour still exists on the dub. i wouldve guess the tape recorder heads are bad or something, but it is the same on several cams. shopping on ebay for a cheap DV Passthrough. found a few in the 30-50 range. may suffice. if teh camera is reviewed as having "bad lowlight" and "bad noise" that wont affect passthrough will it? thats just with the viewfinder, right?
