Not necessarily. If you use a consumer VCR, you're going to get dropped frames, and any FW A/D video converter is going to handle that badly. Some, like the Pyro A/V, will insert noticeable pauses in the stream. At best you will get occasional artifacts or choppiness. That's what a timebase corrector is for, and the Canopus unit I mentioned is the cheapest way you're going to get one.

If you use a prosumer or professional VCR, you will get better results, but a frame will still drop now and then, and the VCR will not be cheap either.

Garbage in, garbage out.
