I've connected a Hauppauge WinTV-HVR-1900 to my Ubuntu 10.10 PC and used the instructions here to install the firmware and test that it is detected using dmesg. Detection is successful.

The WinTV is connected to my TV using component connections. I run this command to enable the component interface: v4l2-ctl -i 1.

Then I use cat /dev/video0 test.mpg, and that file is created and plays perfectly with video and sound.

However, when I try to play /dev/video0 in VLC Player (and other players), I just get a black screen. I also try the v4l2-ctl -i 1 command before I try it in VLC, but I still get a black screen, and when I use v4l2-ctl -I, it shows it has connection 0 again (Television), so it reverts back to connection 0 instead of connection 1 (component).

So I'm a little stuck with getting VLC to get a picture, even though the CAT command works fine. Anything I can try?
