It isn't an MPEG file, it an AVI with MPEG-4 video: eric% xxd -l 128 amsn2-v4.mpeg 0000000: 5249 4646 324f 5800 4156 4920 4c49 5354 RIFF2OX.AVI LIST 0000010: 7622 0000 6864 726c 6176 6968 3800 0000 v"..hdrlavih8... 0000020: a086 0100 4871 0000 0000 0000 1009 0000 ....Hq.......... 0000030: 7403 0000 0000 0000 0200 0000 0000 1000 t............... 0000040: e902 0000 3702 0000 0000 0000 0000 0000 ....7........... 0000050: 0000 0000 0000 0000 4c49 5354 9010 0000 ........LIST.... 0000060: 7374 726c 7374 7268 3800 0000 7669 6473 strlstrh8...vids 0000070: 464d 5034 0000 0000 0000 0000 0000 0000 FMP4............
