Mplayer complained about some missing vdpau lib so that did not work out
but I tried svv from moinejf.free.fr and got the same results as
previously described.

I can see the plusses fine but maybe something got mangled so here's
what is prepended with a "+":
if (sd->sensor == SENSOR_POxxxx
sensor == SENSOR_PO3130NC)
sensor = sd->sensor;
Just checked git.linuxtv.org where the latest vc032x.c code lives and it
has changed such that this patch no longer applies. My C foo is not at
kernel driver level so I'll leave it at that and just use one of the
webcams in my bag.
