Each capture freezes in exactly the same spot, but across captures it
varies.  I originally tried xine, but it's not playing sound and I'm not
sure how to tell it to use spdif.  I could just watch the video and see what
it does at that point, but I'd prefer to have the sound as well.  Any idea
how I tell xine to use spdif for sound?
