Can’t your BD player play back stuff from USB?
Nothing bigger than 4 GB.
That’s probably a fat32 issue. Fat32 can only handle file sizes up to 4GB. If your BD player supports any other filesystems for example ntfs, ext3/4 or hfs+ try formatting your devices with one of them.
Bingo. It only accepts fat32, I’ve researched it thoroughly. It’s like a five year old player.
