Yesterday I purchased a portable hard drive, hoping that if I plug it into the USB port on my Panasonic blue ray player I would be able to watch MP4 files through my tv. I formatted the hard drive the FAT32. Once inserted the lights come on the hard drive, but only MP3 files load. I wasn't sure if the USB port on my blue ray player was only specificity designed for MP3 files, so I then tried to convert the files, but they still would't work. I also have another issue. I wasn't 100% sure if potable hard drives were able to work through tv's. But I plug it into the USB port on my teach flat screen tv, no lights were on the hard drive and I couldn't find the setting on my tv that the hard drive would work from, there isn't even a USB button on my remote, what setting is it under? help me please!
