Is there a way to control the final gain on the analog encoder video DAC output (without performing a digital pixel-by-pixel multiply on a frame-by-frame basis)? We'd like to control the gain at the DAC, if possible.

Yes, there are registers available to control gain at the analog video back end. See VPBE UG for more details (http://focus.ti.com/lit/ug/sprue37c/sprue37c.pdf)
