Are these VCR's really digital? It seems a very expensive way to do the frame buffering for the prices these VCR's sell for. Could an analog approach be used instead. I could conceive of using a Charge Coupled Device (CCD) to grab frames. I'm not sure this is what they do but having used frame buffers here I know they're not cheap.
