the bin file is the image, which contains the movie, the cue file is just an instruction for your program how to burn the bin file.
if you want to merge them to one file use isobuster
www.isobuster.com
the free only functions are enough, no need to register
open the bin file, search for the mpeg in it, it should be named avseq.mpg or something like that
right mouse button -> "extract, but filter only m2f2 mpeg frames"
then you´ve got your mpg on your hdd
do it with all three files, then merge them together
just a tip:
when you´ve merged them use mpegmediator to extract the audio , headac3he won´t accept the audio, if you demux with tmpgenc
