So you have tired without audio (-a 0). and as recording size 720x576 ?
You know that the input selection works different for "generic" v4l 
cards. So pleas also try other inputs. How the input selections works is 
described in the lavrec manpage.

 From the output I would guess that you are not root, please try it once 
as root.


auf hoffentlich bald,
