I use Ripit to back up my DVDs to my hard drive and convert them for my ipod. Tonight I decided to go a step further and download Roxio Popcorn 4 so I could burn off physical copies of my discs to have on hand. It shows in menu that my DVD files have been resized to fit on a 4.7 gb disc, but when the multiplexing is done is says "Not enough space on disc, 6.4 (or the such) gbs are needed, you do not have enough room on disc." This is somewhat infuriating because I thought the whole point of the program was to shrink DVD 9 file sizes down to something that can fit on a 4.7 gb blank disc. Anyone run into this? Thanks in advance for any help.
