>I need a simple method to convert RGB video (1.00 V p-p) from a Booktree BT101 video DAC into composite video, preferably using only one IC and some off the shelf components.

Check the National Semiconductor Special Purpose Linear Devices Databook
for the 

	LM1886 TV Video Matrix D to A
and the
	LM1889 TV Video Modulator

These two along with a suitable sync generator will produce both
composite video and RF channel carrier.

For a sync generator check the RCA Integrated Circuits for Linear Applications
databok for the CD22402 Sync Generator.
