Or think about mplayer-g2-PVR, with simultaneous display and encoding
of video. Maybe you have something like:

                 ,-> vf_madei -> vo
                /
tvin -> vd_raw <
                \
                 `-> ve

...or...

                              ,-> vo
                             /
tvin -> vd_raw -> vf_pullup <
                             \
                              `-> vf_scale -> ve
