Yeah ok, but Dave is playing back the MAME version on a CRT. I know what you mean with your description, but this is "normal" and thats how interlace look on modern monitors. Like i said, it could also be just Youtube compression. I need to catch some of the MAME LD stuff, to see it for myself.
The posts where they talk about it
Quote: Dave: It would be better to build a little board capable of capturing the signal before the audio was split off, that way you'd get as close to a perfect capture as possible. The circuitry in the LDV8000 introduces a moderate amount of noise, but given the **** quality of the FF disc, where multiple generation edits have been done with some seriously noisy gear, it doesn't really matter that much.
For playback on a PC, you'd most likely get better results by just using a capture card as it will have a TBC, 3d (hopefully) comb filter, etc. As I was ultimately going to play out composite, going through that process and then back to composite again would degrade the picture. The Mame image, for instance, looks fine on a PC, but nasty when remodulated. The explosions, in particular, are covered in artefacts where the comb filter hasn't managed to get rid of the crosstalk between luma and chroma.

Dave´s answer: Because the artefacts are clearly visible when playing Firefox in Mame. Tongue Mind you, it's arguable that the effects of composite to RGB and back again would be dwarfed by the poor results produced by Firefox's demod board.
