Hi

When I try to playback videos I have recorded on my iphone 4s (5.1.1) all I get is the sound but no picture, any ideas what could be causing this?

Thanks in advance.

I had the same problem and I'm pretty sure I eventually found out it was due to safari download manager. Whenever I would play videos I record I got only sound and black screen. I put my phone in dfu mode to test if it was my phone or something by the jailbreak. When I was in dfu mode the video played fine so test that out. Once I found out it was because of jailbreak I deleted a couple jailbreak apps one by one and found out it was because of Safari download manager. I also couldn't play any videos from the Internet. Hope this helps
