Hi. I'm using the Prism Tube to record my daily motorcycling commutes. Until last week, the device recorded everything in files of about 4.2 GB called "PRIXnnnn". But a week ago, it suddenly started to split files after about 330 MB called "PRILnnnn". Not that much of a problem, except that the last half second is repeated at the start of the new video, so if I want to combine (as in concatenate) video files, I have to meticulously edit out half a second for each half minute. Very annoying, especially since this behaviour started randomly (apparently) and when it still recorded in big files, the half-a-second repeat didn't happen.

I made no changes to the device, to the SD card or to my usage of the device. No firmware, no updates, no different cards, nothing. It just started doing that out of the blue.

I usually format the card after every day of recording, so I have also formatted the card a number of times since this started to happen.

What's going on?
