All this flag does is set a single bit in the MPEG header that tells the
*decoder* what order to decode the fields in. For a software decoder
displaying on a progressive display like a Computer monitor *the flag can
have no effect*: both fields are always displayed together.
To check if field order is wrong you have to use an interlaced display. With
practice you *can* usually tell something is wrong even on a progressive
display but thats not easy to explain in text form.
For Movies transmitted in PAL it is easy: simply look to see if
at cuts between scenes you get a frame with one field from one scene
and the other from the other.
