I have the same problem. I have the Roku ultra. I've had it for about 10 years with no issues at all until a few days ago. My RMP stopped recognizing any MP4. I've played these same videos for years but now it doesn't see any of them.
Pointout. My Roku Ultra is on OS11 and RMP is playing my mp4 files (AVC/AC3 and HEVC/AC3 codecs) just fine. I also was able to play a MKV file with HEVC/DTS. This is from a Toshiba 60GB USB thumb drive. I do have the Roku going directly to my Denon, then to my Sony TV.

OK, I tested my external hard drive, a Western Digital 1 TB drive formatted as NTFS. The only media files on the drive are all DVD rips, so MPEG2 video, AC3 audio and MKV container. Every file I tried played fine. This was with my Ultra 4800 using RMP and 11.0 build 4000something. I don't have the exact build number, as there was an update available after I tested and I went ahead and installed it. My version now is build 5003.
You might check and see if there's a new OS update available for your device. I don't know if b5003 is specific to the Ultra 4800 or if it's good for other devices as well. Perhaps this update will fix the USB issue.
