Recover Mpeg4 - but no sound

[stangspringer]

Dear All

I have a Sanyo HD2 camcorder. I accedently lost all pictures and movies on the card. It is 8 gb with my daughters birth and upbringing. I am so sad.

Anyway I have tried 8 different data recovery applications. I can recover everything. There is not a single pixel missing on the pictures.

In the recovered video files, however I have no sound. The camera encodes the movies in mpeg4. It is not a codec problem. When I transfer a new video from the camera to my pc it works perfectly with sound. When I transfer a recovered video file back to my camera, it will not recognize it.

I am desperate. Its so valuable to me having these films. Anyone with ideas on how to recover with sound???

Thanks a million in advance.
