Are you using AccessGrid-2.3-5.i386.rpm by any chance? I broke webcams based 
on the pwc driver (or more generally devices
that only support YUV420) in that release after adding support for 
Kensington webcams (and other RGB24 capture devices). See:

AccessGrid-2.3-6.i386.rpm works with both pwc driver webcams and RGB24
