Hi,
This is a known problem in 0.6.0 fixed by this commit:
http://linuxtv.org/hg/~hgoede/libv4l/rev/89fba654c7ea
You can get a snapshot of what will eventually
(soonish) become 0.6.1 here:
http://people.atrpms.net/~hdegoede/libv4l-0.6.1-test.tar.gz
Upgrading to this should fix your problems.
Regards,
Hans
