That is a bug in the driver, I've already mailed the author about that.
What happens is that :
- GnomeMeeting requests YUV420P
then
- GnomeMeeting requests QCIF size

But the driver fails at the step 1 without I have been requesting any
size yet. That is the only driver having that problem and that is
recent.

I could invert the ioctls but it could potentially break other drivers.
Check that if there is an option to the module to specify the default
size when opening.

However, I know nobody having problems with pwcx.
