I'm having some issues with my video recorder... When I replay the videos they seem to be choppy and slow, it's like the frame rate momentarily slows to a very low figure. The sound does not appear to be affected, only the video... Anyone else having this issue? I have enabled debugging and most of the other fixes listed I can find on the web but nothing appears to fix the video camera from lagging.. Could it be my memory card? I'm using a SanDisk 16GB Class 2..
