Use IsoBuster to see what it is:www.isobuster.com/
I suspect the file is an MPEG that has an .iso extension,try changing it to .mpg and see if NeroVision Express,etc accepts it.
Thanks dodecahedron, hoxlund for the "Imgburn" link/info, Imgburn couldn't open it either, however I finally found a small tiny program Daemon Tools 4.03 (1406KB) which produces a "Virtual" drive and I could mount the iso file and view it with any players with full access to the interactive menu in the movie
Hey burninfool, you are good
, as soon as I changed the iso file extention to mpg, all the players could play the movie! (but could not access the interactive menu in the movie however) UltraISO couldn't open the iso file so I didn't bother with WinISO. Yes, NeroVision express accepts the file in mpg extention but would only play (during preview) the first 2 mins or so.
