As Robert Day says, UNIX files don't have creation times. They have a ctime
which is "last change to inode" - it updates on chmod, rename etc.

But pretending ctime is creation time, which may be close enough for
your purposes:

  find /myth/recordings/ -maxdepth 1 -name \*.mpg -ctime -1 ! -mtime -1 -print

remarks. Your '-name "*"' seems redundant.

If you do end up comparing lists (should not be necessary for your problem,
since you can do all the testing with find), "sort" and "comm"
are your friends.
