The manual says the format is .MOV files holding:
Picture: H.264/MPEG-4 AVC coding.
Audio: 48 ksps 16 bit Linear PCM coding.
I had the recording option on the camera itself set at 640 pixels and 25 FPS, set also to 'High Comp (IPB)' and not 'Low Comp (ALL-I)'
Does that shed any light? I have already only been searching for apps that restore corrupted .MOV files, not other formats, BTW
