1) the window xawtv uses to display the frames is not resized to a particular resolution that xawtv successfully asked with the appropriate ioctl. I have to do it manually. Any idea? (I don't think the problem is the window manager).

xawtv simply doesn't resize the window on its own.  Instead it asks
the driver for a frame size matching the current window size.  If it
doesn't fit (because the hardware doesn't support random image sizes
for example) the image is centered.

IMHO this is better from a usability view.  The user should control
the application, not the other way around.

2) The frames are grabbed using the YUV422-16bit format (original video), but when xawtv try to display them, the colours vary from green to purple only (i am not an expert, but i think the u or v value is setted to 0).

Are You sure about your frame buffer pixel format ? It occurs with me when I use pixel format YUV422
in a RGBP16bpp frame buffer, witch give a nice effect.
:)

bytes swapped?
