Im having the same problem and I think it is the prerecord setting.. I had 2 sec. pre record and each video would play two sec. and stall for a sec. or so then I increased pre record to 4 sec. and the video stall didnt stall till 4 sec. into the video play back..
So not sure yet still testing ..but I think it has to do with the pre record.... Ill let u know in the next couple days gunna do some testing...
turn pre record down or off and see what happens...let me know how it turns out.
