Alright, though that doesn't seem to be what the datasheet says. (http://dl.ivtvdriver.org/datasheets/cx2584x/CX2584X%20Linux%20DS%20102538A.pdf) One of the the inputs that figures into the (H|V)SCALE calculation is the ratio between the active region and what we want the output size to be. -- Tyler Trafford ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
