Pal or NTSC?

Is there an easy way to tell if an mpeg file is PAL or NTSC?

I'm burning a DVD with Toast right now, I have about 9 movies, and I keep getting the error 'A disc cannot contain both NTSC and PAL media'.

I'm guessing one of them is PAL, but have no idea which one.

They are all Mpeg1 files.

yikes.
well, get info might say something.. or even if u opened the files in some sort of editing program.

other then that, PAL tends to look longer where ntsc looks wider.
only on a tv though.

good luck
