Why do you need it on a DVD? If it's 700MB, then it will fit on a CD. You can probably get up to about 740MB onto a CD, if you're lucky. You could also compress it using a program like <a href="http://www.rarsoft.com">WinRAR</a> with the maximum compression to shrink it by about 30MB. You could also use a 1GB USB flash drive if you have one. Or if you have a digital camera with a large (1GB) SD/xD/MMC card, you could use that.

Otherwise, you could use FileSplitter, mentioned by Allie in <a href="http://forums.eyesonff.com/showthread.php?t=73472">this</a> thread.
