I totally overlooked that due to [ ] Enable Video For Linux API 1
(DEPRECATED), thank you.
However I have some trouble getting mplayer/xawtv to work:
mplayer:

WARNING: YOU ARE USING V4L DEMUXER WITH V4L2 DRIVERS!!!
As the V4L1 compatibility layer is broken, this may not work.
If you encounter any problems, use driver=v4l2 instead.
Bugreports on driver=v4l with v4l2 drivers will be ignored.
