yes, I do mostly the same thing as the VIDEO_STILLPICTURE ioctl is doing
internaly. I just make sure, that no matter how large the i-frame is,
400kbyte of picture data are sent to the card. The VIDEO_STILLPICTURE
ioctl also works some magic on the i-frame, which at least for the DVD
type i-frames is not needed.
