Sorry about that, I guess Olli tested on i386, there still were 32
-> 64 bit struct conversions wrong/missing.  I just updated the
patches, now skype's video test also works for my camera using this
Linux libv4l like mentioned above:

	http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/11/Fedora/i386/os/Packages/libv4l-0.5.9-1.fc11.i586.rpm

 Links to the patches again:

	http://people.freebsd.org/~nox/dvb/linux-dvb-v4l2-8-test.patch
	(for 8, this is what I tested)

	http://people.freebsd.org/~nox/dvb/linux-dvb-v4l2-test.patch
	(for head, should at least apply now)

 Enjoy! :)
