I have skimmed through some of the posts about compression and haven't seen an answer I am looking for. (1) I have a 43gb blu-ray disc, but I only have 25gb blank discs. Is there a compression software out there that can do this? I have used imgburn to get the movie onto my hard drive with no problems. (2) I have seen lists of dozens of softwares to use while burning/ripping blu-ray. Can Imgburn compress to under 25gb or is Imgburn strictly an exact copy software? With DVDs, shrink would compress the files to 4464MB, and then you could use Nero to burn to disc. Is Blu-ray not that simple yet? Sorry if this has been posted before, but I am racking my brain trying to figure this out.
