SD Card Playback issue

I have an OG cam. SD card playback WAS great. I used the camera for a 30 day time lapse and now SD card playback is horrible. I have reset the camera, Re formatted the SD card. I go back to watch an event thats noted with a Motion or Sound symbol, it plays and after watching video it freezes right around the time of the event and audio plays for continued 2-3 seconds and thats it. IF i try and record the playback the record timer start up top , video freezes right around the time of the event audio plays for continued 2-3 seconds. as noted Video freezez BUT the Record timer is still going. i could let it go for 20-30 seconds but Once i touch the screen anywhere the timer stops. when i watch the video in my camera roll the video stops right when the video freezes.

noone?
