Repairing MP4 files?

Question

I have some .mp4 files. Recently they don't work anymore. No matter which players and codec packs I use, the files show as corrupt, damaged, can't render etc.

I've also tried using MediaInfo to extract information from the files but it doesn't show anything.

Is there any possible way to repair them?

Will the files play on another PC? If not, your hard drive crash damaged them, and they may well be unfixable. One thing I've done in the past is use mencoder or a similar package to convert the damaged file to AVI. This at least recovers the undamaged portion.
