New Firmware issues list with missing mp4 files

Hi all,
A couple of issues with the new firmware. Main one is i cant get it to see all the mp4 movies in my media library. If i go to the file listing i can see them. Even doing a rescan or complete rebuild of the library hasn’t helped. Other folders are fine. Its just in two particular folders.

Im hoping the performance issues its having a related to doing the media scan, it doesn’t say its still going but i wonder if its still doing something in the background.
Cheers
Miles
