IIRC, John Shutt said some time ago that there is no actual interference problem between the chroma carrier and the audio carrier, even at 30 fps, in all NTSC receivers likely to exist today. Is this not the case? If true, then wouldn't ATSC offer the opportunity to begin producing content at a true 30 or 60 fps? Since that's a legitimate option? Seems to me that composite or S-video NTSC wouldn't care anyway, and any laggards using the RF interface shouldn't either.
