I am having a problem playing back movies shot on my iPhone 4S on my computer after update

I posted exactly the same issue yesterday. In a way I am glad it is reproduceable, I thought it might have just been me.

I figured it out!!!! After I dont know how many hours. Its Quicktime!!! I went back to the previous vesion and now it works. So the new update for quicktime7 dosent support the iPhone camera videos. Dont know why. So just remove quicktime 7 and download the previous version. Or right click the icon and it had that option

Thanks DCM32. I am not finding an option to use an earlier version of Quick Time via the icon. Clarify if you can. I also tried to find an earlier version of Quick Time and found 6.4 on the Apple website. Tried to delete the 7.7 version and install the 6.4 version. Same issue but the screen is white instead of black. Which version of Quick Time are you using and where did you find it? Thanks for the help.

I reinstalled 6.4 version : ) I found is on here. Make sure its the right one for your computer. Im using windows

Ifound some earlier posts on sthe same issue. Since 6.4 didn't work (for some reason) I tried QT 7.6 as an earlier post suggested. Now it all works just fine. Must be something in 7.7 that is casuing the issues.
