How can I load a Video Player App on my Nook Color without google play? My son's nook color is incompatible with google play, and the default video player app wont play local video files I've uploaded to his nook's harddrive via usb-cable. How can I download a new video player app to his nook 'without' google play?

I am using software version 1.4.3 and am not interested in solutions that involve rooting the nook, or rolling back to a previous version of the software.
