as the v4l-dvb-kernel updates some parts of the video4linux interface, just
building wis does not work. if you want to use the Plextor M402U you have to
use a patched (this is evil) Module.symvers. Either use the one provided or
copy the symbol hashes over from the *.mod.c files. generate the headers
start spook and watch video through vlc (mplayer) from it
vlc rtsp://localhost:7070/webcam
for the Plextor, it can NOT be used at the same time as the Pollin,
v4l changes the kernel symbols and wis can not work with that
re-install the kernel if you want to use it
changing the kernel symvers somehow does not work
