Kind of a technical question about the quality of the Shrink compression algorithms vs the DVDFab Decrypter algorithms. Has anybody qualitatively compared DVDFab to Shrink for a resulting backup DVD of an original that requires, say 80% compression, to fit on a DVD-5 blank? When using Shrink I use the Deep Analysis and Adaptive Error Compensation (AEC), maximum sharpness, as the compression options. DVDFab doesn't seem to have any options, however, and it does compresses a whole lot faster than Shrink. Also, I play all DVDs upscaled to 1080p, both original and backups, on either the Sony PS3 or the Toshiba A20 (both Hi-Def players), so backup quality makes a difference. I'm just wondering if I should continue to use DVDFab to write to a file and then use Shrink to compress before burning. Any opinions would be appreciated.
