[MPlayer-users] converting a .mov file with mencoder

First, a real MOV file can contain other codecs than JPEG.

Second, file is not infallible: all it takes for it to report a file as
"Apple QuickTime movie (unoptimized)" is for the file to have "mdat" in
ASCII as bytes 4 to 7.

$ file blah.txt
blah.txt: Apple QuickTime movie (unoptimized)
$ cat blah.txt 
The mdat tag is not reliable.
