Thanks Mate,
Downloaded the recova software but unfortunately
still no video. At the completion of each short video
I see a processing bar which goes from 0 to 100%.
All watchable videos reach 100% processing but all unwatchable
ones only go to about 40% and stop.
Don't know what the processing is but I imagine it's some sort of
metadata for each video file. This leads me to believe that it is the
memory card that is the problem, maybe it can't process the data quick
enough.
If you can find that spare card for the weekend that would be great as I
can see if the processing bar is working after each video.
