I haven't worked with DVI yet.

Anyway what is important to understand is the format used by the DVI video decoder. What kind is it? RGB? 4:2:0 YCbCr?

Another important thing is the order of the video processing stages in the video pipeline. My best advice would be to put the framebuffer as the last stage, just before the CVO, and enable both frame dropping and replication. In this way it will fully compensate underflows and overflows of the video pipeline.

If you provide more details about the video format I can try to give some hints.
