Sounds like you've got something similar to the idea in Apple's QuickTime of
custom media handlers (admittedly not fully developed in QuickTime 1.0). Do
you have anything resembling the QuickTime movie format, which allows you
to distribute canned presentations that can be controlled through a standard
player interface?

Will your digital video support be tied to DVI compression, or will you
allow alternative hardware/software compression algorithms to be plugged in,
a la QuickTime? Also, will there be a standard API for video capture that
other card vendors can support?

I'm not fond of benchmarks. I prefer my schmarks to be straight.
