Hello, Currently on BI V5.3.2.11. Recently I have been having trouble viewing most of the saved mp4 files either in BI or directly off the hard drive. If i try to open the video within BI (from the preview panel on the left side of the interface) I get the message "this type of file may not be viewed while open for recording". Most of the videos listed there have a red border around them like they are recording. BI continues to write new mp4's as the cameras are triggered but they all seem to remain in a recording state. What I do not understand is why this is happening to all of the videos. Since this afternoon there are 19 videos in the folder with only one viewable. The cameras are set to record MPEG-4 (MP4) and Direct-to-disc. Any help would be appreciated. thank-you
