Most HD TV episodes are released at a 1.07 GB size, which will fit four episodes on a DVD, all snug and nice.
Some episodes are, however, released at a 1.43 GB size which fits three episodes on a disc.
In the case of Dexter, all of Season 2's episodes have been released at 1,07 GB, exept for three of them which were 1.43 GB. This makes it difficult to fit the files on DVDs (at least in the right order, or without wasting space), so I have shrunk E02, E05, and E07 to the standard 1.07 GB for an HDTV RIP.
Shrinking have been done in MeGUI, x264: Profile HQ-slowest. The files will probably stutter on a slow computer.
