It will hook up, but SD material is usually 720 x 576 (in the UK, less in the US) no matter of it is 16:9 or 4:3, so your editing software can deal with this in two ways. lose the edges of the 16:9, or stretch and then lose the top and bottom of 4:3. The stretching and then ‘throwing away’ means you will lose resolution. You can even stretch a bit and shrink – so you distort a circle, but only a bit. If you play your old tapes, I suspect the image will stretch, because while there are data flags to indicate the aspect ration, because the SD frame size is fixed in pixel count, different models and makes often get it wrong. So anything you capture might need adjusting depending on the format you select.
