I've made mistake in the first message, I'm sorry. My camera works with 640x480 and ~10—15 fps.
I run "mplayer tv://" and see 640x480 resolution and less than 30 fps. If I run "mplayer tv:// -fps 10" — I see the same frame speed. "mplayer tv:// -fps 5" — I really see 5 fps. I really don't care in which resolution my camera should work, but I want to get 30 fps. Also, my CPU load is ~25%, the video card works with hardware acceleration. I've tried different mplayer video drivers (xv, gl2, etc) and I see the same result.
