This patch fixes the problem of vic only capturing an even or odd frame plus
the my early patch for missing frames with resolutions higher than 320x240
in rgb mode.
The yuv422 patch introduces a minor bug in that a green line appears at the
bottom of the captured window . There is no easy work around for this right
now.
If no one complaints about the patches not working , then I suggest that
that they should be applied to the released version of the bt848 driver.
Enjoy,
Amancio
