What do you mean be "works incorrectly"? The new gspca drivers
only support v4l2 and don't do conversion in the driver.
Well, indeed with v4l driver the mplayer shows a messed image with
swapped lines and weird colors, but it fails at all with v4l2:

Hmm, mplayer should support it all on its own. But you have to set some options, tv:// won't be enough. Here is what works for me:

mplayer tv:// -tv driver=v4l2:noaudio:width=640:height=480:device=/dev/video0 -fps 30

You need libv4l
to do that (either built into your application or as LD_PRELOAD
wrapper). I was going to upload that package to extra just now, but
the server with the source tarball is unavailable right now.

Ok, I'll try libv4l, thanks!

Should be in extra now. Version 0.5.2 should hit the mirrors soon. I think it even fixes a bug with your camera, not sure.
