Okay, I don’t know why you would want to split the Movie in two, just get a BD-R DL that holds 50Gb. I know that the Dual Layer Disks cost more, but you defeat the whole concept of HD Blu-ray. I believe in doing Back-ups to enjoy the Movie in it’s full splendor. I enjoy watching my Back-ups more than the Original Disks, because I only Back-up the Movie and take all that other junk off, and it Stops and Plays better than the Original Disk. You can find some good deals on BD-R DL, on eBay.
