Same issue here... Anyone?
Plugged in a usb drive with .mp4 files in the “Rear” USB port. When selecting the port as the media source for the rear screens it just says “empty” and doesn’t find any files.
Does anyone know what file types are supported or how to resolve this issue?
Since you haven't gotten much of a response, try using a USB drive that is smaller than 64gb - if that works then the format of the drive matters....
So... after tons of trial and error here's my (Kind of) simple fix. What was getting me was that i was using a 128gb flash drive... most of them come formatted with either exFAT or NTFS file systems... and Windows will not let you format them for anything but those two either (They don't like that the files can not be bigger than 4gb). So... I used a free program (EaseUS: Format 128GB USB to FAT32 with USB Formatter and PowerShell) and used that to format the larger USB Drives (I used these: https://www.amazon.com/dp/B07D7PDLXC?ref=ppx_yo2ov_dt_b_product_details&th=1) to FAT32. Then I added my .mp4 files to the drives (Formatting will erase the drive so put those on another drive while you format and then move them back after).Same issue
