mpeg-ts in mov start with a mdat atom, apart from that there is nothing 
that reminds me of a mov (no other atom iirc). Both sample files we have 
are detected by the mpegts probe code with a score of 100 when testing 
2048 bytes. But the mov detection is "quicker" although the files cannot 
be read at all, only an error message is shown on ffmpeg -i input

mpeg-ps in mov are real mov files with all kinds of atoms describing the 
files and the mov demuxer was always able to read the files (it just 
couldn't actually decode them).

I don't think the same approach can be used for both type of strams.
