Heh, maybe not. :) The vdr list is at vdr at linuxtv.org (I'm not sure
but I think you need to be subscribed to post, see
http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
to subscribe and
http://dir.gmane.org/gmane.linux.vdr
for a `nicer' archive), and the w_scan author's email is in
/usr/local/share/doc/w_scan/README (Cc'd.)
And btw, I now finally can test vdpau myself, and already found out
libva currently seems to work better at least for vdr, more about
that later.
Cheers,
Juergen
PS: and the `general' Linux list for v4l/dvb discussions now is
linux-media at vger.kernel.org - see e.g.
http://dir.gmane.org/gmane.linux.drivers.video-input-infrastructure
