I use DVD Shrink and usually when I burn DVD's they are over 4.7 GIGS. I choose 'Full Disk' mode and just burn the whole DVD, and DVD Shrink does a good job compressing it and then burning it with DVD Decrypter.
Recently I have had a few DVDs that are less than 4.7 GIGS and I try to do the same process, but for some reason when it burns the DVD only about 2/3 of the stuff is there! I don't understand...I open the disk, do full disk, (the compression meter says 100% cause it has no compression needed) and then the files are incomplete (on the c-drive only like 3 gigs are present instead of the 4 that are on the original dvd) and I keep wasting blank DVD-Rs. Please help me, I am a dirty newb that needs a helping hand.
