Open the file with ISOBUSTER (google for it) and then extract, read this How To:
If you dont see the file system of the CD using Isobuster its a dummy.
When extracted play it in FILE mode (it will not work if not).
Try using Videolan (VLC) or MPC (media player classic) to play the file....................you could well have a DUFF (see above).
Your PC has about a thousand times more power than a DVD player, so if it cant play it don't expect your DVD player to.
