Checksums are the same.  All other files still work however the HUGE
rendered Final Cut Pro output, so I guess it is something in .DS_Store.
 Last time I just gave up and recopied everything by a simple cut and paste
and that solved the problem.  I made a small change on the project today,
and I don't want to have to copy the WHOLE thing again just for a small
delta.  I already synced the directories, but the new rendered files are
still un-openable in any application even though the checksums match.
 Really weird.  However, the project will still open and work on FCP.  Just
the 12Gb rendered movie files will not play on anything even FCP.  If I
delete .DS_Store will the system regenerate it with the appropriate file

I know this is a little off topic, but Mac OSX is based on BSD.  You guys
are also the smartest around :D
