It seems that for whatever reason....my SGS won't play back any videos I've previously recorded on it. When I try to play back those videos the player opens, the wheel just keeps going, and when I hit the play button the video comes up,...but it won't play. I can 'step thru' the video frame by frame using the 'double bar' (pause) button, but the video won't play. I've done a soft boot, I removed and reinstalled the battery and it still wont work. I've used my 'Android Assistant' to boost the memory and that doesn't seem to fix the problem. I can play YouTube videos and play music and view photos and play Angry Birds with my SGS, but I can't get it to play it's own videos. I've checked the forums and found some posters are getting error messages but I didn't find any postings noting the 'video wont play' problem I'm experiencing. So, if anyone out there has any feedback on this I'd love to hear it,....so I can watch my videos once again.
