Hi Guys,

The attachments here are sent using tinypic.com.  It's the first time 
I've used it, so I hope it works OK.

I'm using the qv4l utility, but I did try it on v4l2-ctl and gst-launch 
and the results are the same as the one's I shall post here.

Firstly, here is stk1160 s-video for a baseline comparison.  Look at the 
word "File" in the file menu:

- http://tinypic.com/m/i50k8z/2

Now here is ImpactVCB-e composite.  Again look at the word "File" in the 
file menu:

- http://tinypic.com/m/i50k8n/2

The quality is a little worse, but maybe that is just 
Composite/S-Video.  Composite is not working on my stk1160, so I can't 
do a direct comparison.

Now let's look at ImpactVCB-e s-video:

- http://tinypic.com/m/i50k8w/2

It looks like every other line is missing.  I'd guess it's 640x240. I've 
tried v4l2-ctl -v width=640,height=480 etc, but no difference.

You can see it too with images but it's just not so obvious as with text.

Now when I switch back to ImpactVCB-e composite, I get the same problem, 
but after a restart it goes away.

What do you think?

Regards

Stev
