Thanks for your answer.

I've tried using mplayer as suggested in another post. Resolution is 
alright with both composite and s-video (PAL-I). I suppose something 
went wrong with qv4l2.

Nonetheless, I have vertical lines when using s-video at MPEG device 
output (more visible in white areas)[1].

Reading from capture device is alright whether s-video (input=2) or 
composite (input=1) is selected. I've tested it like this:

   mplayer tv:// -tv driver=v4l2:input=1:normid=4:device=/dev/video0

Note that I am using media_build.git and mplayer trunks.

Any idea why I'm getting those vertical lines with s-video from decoder 
output only ?
