If you have S video from the DTV converter or DVD player, you could feed the luma and the chroma of the S video downstream of the chroma-luma separation circuit. That's usually a low pass filter for the luma, and a bandpass for teh chroma. Disconnect those, and feed the amplified (if necessary) luma and chroma signals. Be careful that the luma signal is phased correctly as needed, the chroma signal is less fussy. The sync separator will also need to be fed by the luma signal.
