Hi Scott,
I’ve gone through the exact same experience, and tried every suggestion, unfortunately to no avail..
the only thing that enabled me to view the files was treasured, although if you’ve investigated this you’ll become aware that a fee is involved – and i’ve had trouble uploading and completing their quoting system.. so i’m yet to test the service and am a little skeptical..
so im still holding onto the hope of finding some other way to restore these MP4 files to working order..
i wanted to know if you’d found a solution.. i’ve tried the calibrated plug-in, uploading and restructuring BPAV files onto the original memory card, using different recovery programs, ffmpegx, upgrading VLC player… all with the same result.. recovered media, with all the accidently deleted full size MP4 files, unplayable and unable to be recognised by anything..
has anyone been able to actually play MP4 files after recovering them from a formated card?? these replies don’t seem to take into account that recovering the media seems to somehow alter the MP4 files and render them invalid..
