Yes, AFAIK that command is simply wrong for an mjpeg card. It is
appropriate for a mpeg2 hardware compression card like a
PVR-150/250/350/500.

You can probably use lavrec from the mjpegtools package to capture.

 (but read the whole page, and sorry if the url is munted)

You should start by using something simple like xawtv to check the
card is working. Also do not expect these cards to work in a via
chipset motherboard.
