For what it's worth, I've never been lucky enough to see the "slideshow"
phenomenon using your driver. But the description reminds me of a
frequent problem I used to have using Hauppauge's own drivers and
software on that other operating system. As I recall, the problem only
affected the video displayed on the screen. Restarting wintv2000 seemed
to fix it. Video captured to files never seemed to have the problem.
