PN42C450B

hello. i have a question about my pn42c450b which is a 42 inch plasma. i have a 32 inch LCD (ln32c450e1dxza) and when i connect my usb to it, it has an option to play video's from my usb. i know all the codecs that it plays. but with my 42 inch there is no option to play video's, only photo's and music. (this is from the media play in the menu) my question is, is there a way to get my 42 inch to play movies from usb? i think its kind of weird that a smaller TV would have this option but not a bigger one. any feedback on this would be greatly appreciated. thank you.
