Can’t your BD player play back stuff from USB?
Nothing bigger than 4 GB.
Perhaps you could purchase an external portable hard drive, and put the movies/videos and whatever else you may want, on that…those don’t have that 4GB size limit.
Hah I currently have 600 GB of Star Wars content on my external hard drive. I just keep it plugged into my blu Ray players usb port normally so I can start playing anything right off the bat.
