Richmond,
I good suggestion. Thank you. However, looking at an identical video
clip encoded as MPEG-1 and as MPEG-2 in a test editor shows lots of
gibberish and no obvious text tags to tell the encoding.
Unfortunately, I don't have time to research byte level binary encoding
differences between MPEG-1 and MPEG-2, which is why I was hoping some
LiveCode media guru had already done this and would share.
It was a good idea to try though.

I suppose if you open an .mpg file as a TEXT file it should
contain standard markers as to whether it is encoded as MPEG-1 or MPEG-2.

Livecode 9.x.x uses Apple Video Foundation (AVF) for the LC Player

AVF supports MPEG-1 video but not MPEG-2 video.
Both MPEG-1 and MPEG-2 use the .mpg file extenstion.
Question for any media geniuses on this list: Is there a way in
LiveCode to tell a MPEG-1 .mpg file from a MPEG-2.mpg file?
