Oh.. For all you conspiracy people here's an interesting tidbit : according to this presentation, the original tapes (the high quality Slow Scan tapes which are apparently super sharp) were placed in the National Archives. These tapes are now missing and the only machines available to play them back are about to be decommissioned:
In 1970, the tapes were placed in the US National Archives in Accession #69A4099. By 1984, all but two of the over 700 boxes of Apollo era magnetic tapes placed in the Accession, were removed and returned to the GSFC for permanent retention. These tapes are now missing.
