Again my bad... cheap is not the right term... better said a only SD capable card. I guess Aaron did use such a card (because HD was not common at that time and/or really expensive) and i guess the capturings have broken fields. I think that because, in Dave´s Firefox thread, he is talking about the MAME version capture of Firefox using with the original hardware and that some things are not looking good as the original (in his example the explosions). I watched HD Firefox Youtube videos and i saw broken fields with artefacts, this could be due to Youtube or by the capturing, hard to say. You can live with artefacts, but if you break the fields, motion might appear jaggy/jittering. If you capture interlaced content in progressive mode, this is something that could easily happen.
