could also be a bad reception and that the video is shifted by 1 or 2
bytes to the wrong direction, maybe you forgot to strip of the headers
of your frame (just a guess though)
RGB would look differently.
YUYV uses 4 bytes for 2 pixels, RGB 3 bytes for 1 pixel (so the video
would very likely be bigger).
It seems like that you're displaying the whole videocontent already so
have a closer look at stripping off a few bytes.
