Wondering if anyone can give me any advice.

I was filming using my JVC Everio MG77 , and during filming, an error message appeared (I can't remember what it said). However in a nutshell, when I went back to playback, the file was not visible. I've managed to recover the file (.mod), however, I'm unable to playback the file. The file seems to be the correct size.

I've read a couple of things on the net and attempted to recover it, however nothing has worked so far.

Does anyone have any advice on what I can do, or know anyone who may be able to fix it???

Cheers for any advice.
