change webcam resolution

Hi all,

the attempt to use the image acquisition toolbox for using a webcam was really fast:

video = videoinput('winvideo',1);
foto = getsnapshot(video);

however the desired resolution was not achieved.
how is it possible to change the resolution?

k = imaqhwinfo('winvideo');

gives me the desired Format:

the attempt to use it fails:

video = videoinput('winvideo',1, 'VideoResolution', [1600 1200]);
Error using videoinput (line 319)
The FORMAT specified is not supported by this device. See IMAQHWINFO(ADAPTORNAME).

thanks for any hint
