Videos don't play, are blue (not tinted, I mean blue)

I read instructions here:
https://wiki.ubuntu.com/SkypeWebCams
where it says:

Graphics Cards XV Skype and gstfakevideo
There are a couple of issues that create problems getting webcams working with skype. The gstfakevideo driver will probably get things working provided you have a suitable graphics card driver set up in xorg.conf
There is a highly significant thing called xv this is easily overlooked in the rush to get video working.
you need to install the gstreamer packages and try this out.
gstreamer-properties
go to the video tab and test your camera with the default settings if it doesn't work with the plugin 'autodetect' in 'Default output' change it to 'X Window System (No Xv)' then try again
if that works and 'X Window System (X11/XShm/Xv)' doesn't work then you are using an incompatible graphics driver.

That is the case, output to 'X Window System (No Xv)' works but not 'X Window System (X11/XShm/Xv)'. Do I have an incompatible graphics driver? Where can I download it?

Linux's graphics card support is horrible. Not our fault, it's just the way it is. Have you installed a driver at all for you graphics card? You should be able to find one in "Additional Drivers". What card do you have?

I have an Intel 82830 CGC.
No proprietary driver installed in "additional drivers", only ubuntu's drivers?

"lshw -c video" says that I'm using the i915 driver

No, that should be fine then. Sorry, out of suggestions. It is going to the X server, otherwise you wouldn't be able to see it.
