Jim has all his movies backed up on his network. He'd like to use an SD card to plug in and watch that way. Leo says he can, but he'll have to be sure it's in a specific format by the Blu-ray player, so check he should check his manual. If he's wanting it for travel, he should check out the SanDisk Connect Wireless Media Drive. Its designed to connect to a smartphone and then he can stream to the TV via DNLA. It has a 10 hour battery life too, which is great for a road trip.
