I have a bdp5100
I tried to play movies in a 4Gb usb, it works fine;In a 4Gb mp3, out of expectation it does load as well; But u know with 4Gb, you can only put 1 or 2 movies there and then i tried my toshiba external hard disk (which may include 20 sth movies there), it failed to read anything. is that normal?
