set up smaller zoom level



i have successfully installt atv2 flash. The little black box should replace a macmini, who shows every day only one single website with dynamic informations on a big 50’ tv. The requested site is not optimated to the resolution of the atv2. So it is very importand to set the zoom level smaller than 0.

Can anyone help me to set the zoom level settings smaller, i. e. -1, -2 or -3?

Thanks, Alfonso
