I know with audio. WMA was much smaller than AVI.
It may be worth doing a conversion just to save space.
At this stage, the main focus is obviously to get the device to complete the function. I agree size can become equally important since I am NOT comfortable manipulating what I refer to as a fragile SD card and tray.
