Welcome to CD Freaks.
Nero Vision shouldn't have much problem converting movies over 700mb as far as I'm aware. It'll convert these to fit either a single layer DVD (DVD5) or a dual layer DVD (DVD9) or to formats that will be burned to a CD (VCD/SVCD)
To view these files on a standalone player you either have to have a Divx compatible player, where you just create a data disc , or convert them to either VCD/SVCD or DVD movie format.
To be honest I'm not quite sure what you're asking here.
