I backed up a 'flipper' DVD recently for a friend who was annoyed at having to stop half way through to flip the DVD. So I started off doing the obvious with DVD Shrink 3.1.5. I ripped the 'top' side to hard disk and left the 'bottom' side in the drive, opend the files and the disk and re-authored.
Due to what I can only see as a bug in Shrink the compression settings were inconsistant, in that it would not compress the 2 titles [as it saw them] equally and no amount of tinkering would allow me to manually set them to anything like close. All I could do was compress the 2nd title by a max of 1% and the first by a max of 50% leaving the movie too large to fit on a DVD-5 - not to mention. So I ripped them both uncompressed to the hard disk using Shrink and got Title 1 [Top side] and Title 2 [Bottom side].
OK, by now you may be wondering why this is in the CloneDVD forum..? Well, after the 'fun' with Shrink I fired up CloneDVD [220.127.116.11] and Cloned DVD Titles 1 and 2 to compress them to fit on a DVD-5 So far so good. Before burning I played the files from the HDD using PowerDVD 4 and skipped ahead to the end of Title Set 1 to find that at the end of the last chapter playback stopped. I did the same with the uncompressed files output by Shrink and the movie played on with a slight pause [no worse that that of a layer break].
So after that out came Shrink again and fortunately this time the compression was applied evenly across the 2 titles.
I was wondering why the difference in playback between Shrink and CloneDVD, and if this behaviour could be configurable?
