You still have to mess with a Hex editor to append the header onto the video part... but after you do it it works correctly. Make sure you turn on hidden files.

A tutorial of this can be found on Chuck Lohr's website (http://www.chucklohr.com/808/#RecoverZeroLengthAviFiles)

The reason I bring this up is because I am having the same zero length video file issue with my 808 #11 HD, but I am unable to find the header (atleast I gave up after line 70000).

Anyone have any fixes?
Well if you can't recover it, it's lost, isn't it? The header is the very FIRST portion of the file, you shouldn't have to search for it. BUT, the header fix that Chuck talks about is specific to an .AVI file format, NOT a .MOV file format like the HD key cam writes to the card. So the identification procedure he talks about will not work, and is the reason you couldn't find it.

When you say you get a zero length file, does it leave any icon that shows up as a regular file, but with zero bytes? Or, are you saying you recover some file fragments that are totally hidden with no visible indication there unless you run a file repair program? I've not bothered even trying because I dont' know what the .MOV file structure looks like. Maybe when I get my replacement camera back, I'll run a test to see if anything is there when the battery dies.
