Programmers,
See my thread in the General Forum, about a programming technique that can make realtime software-based perfect 1:1 synchronization between just about any DirectShow-compatible capture card, and the output Radeon graphics card refresh rate:

You should implement this kind of alogorithm using the PowerStrip API in all the great live video viewer/processor/filter applications.
PowerStrip API allows realtime on-the-fly dynamic control of the output graphics card refresh rate in tiny increments like 0.001 Hz (possible on Radeon cards). This makes genlock possible, by slaving the output refresh rate in a software-based manner using PowerStrip API to the capture refresh rate.
