Downloaded a 7+ Gb movie with extras, trailers etc and which is too long to be burned normally. How can I go about it? I don't wish to leave anything out. Thanks.
Assuming it's in DVD format and you want to burn to a standard blank, you can try compressing it using DVD Shrink. Optionally burn it to a DL disk. There's a consensus that the best blank is Verbatim DVD+R DL burned using ImgBurn.
There's a guide here written by the creator of ImgBurn. http://forum.imgburn.com/index.php?showtopic=4643
