Well, now that I actually have a working cable, the card seems to work
fine (yay! :) ) and I'm getting a beautiful picture from /dev/cxm0.

However I am having some trouble selecting different geometries. Using the
default geometry (which appears to be 720x576) there are no problems, but
with any of the others, things get stretched out, the image is clipped,
and the compression seems really high (i.e. I'm seeing huge compression
artifacts) at the 480x576 resolution.

I have some example snapshots of the different geometries I tried online at:

(created using VLC's snapshot function)

The reason I don't just stick to the default geometry is that the
compression is too low; the captured file increases by about 1.1MB per second.
