Just open Nero, new, ISO, then click the 'Open' button at the bottom. is it a DVD image? or a CD image? is it a VCD movie or shall i read my crystal ball?
sounds like a VCD of a movie. burn them both. disk 1 and 2. if your dvd player supports CDRs and VCDs - it'll play it. otherwise http://www.videohelp.com/ cause you'll have to rip the mpg2 dats onto your hard disk then, either combine them using some video editting software or chuck them on as they are using nero vision - but i can't be arsed to go thru that. we u the nazi lover from last week?
just open nero, select burn image from one of the menu's at the top and locate the cue file then burn away. piss easy what version of nero are you using and what version of windows (& service pack)
