hi all, i normally watch movies by connecting hd media player to my tv and using files from external hard drive. works fine. however, after unplugging it and trying to plug them to a different tv (which did not work), i plug them back to the original tv that i used earlier but did not work. when i try to read the files in my computer it is working. when i plug a memory card or other usb into my media player also works fine. so i''m thinking my media player is not recognising the hard drive any longer. any idea how to fix this?
