Read the manual available online in the products page. Not sure if I got you but the 990 does not do any video processing. All that will come from the source. For each source you can tell the 990 which codec to use as a default and then you can change them with the remote while watching. Realize also that the 990 does not decode any of the newer lossless formats but it does have analog inputs so the BDP can do the decoding and get it to your audio.
