[QUOTE=meeshu;2760397]I’m wanting to backup several movie and TV DVD’s and at the best quality. However, some of the original DVD video’s are not of the best quality (either a bit specky or grainy, and/or at low resolution).[/QUOTE]
If it was made from Film to Video and it wasn’t properly filtered or edited to fix those specks or defects from the start doing it again won’t change it-it will always be there.
[QUOTE=meeshu;2760397]I’ve tried several DVD copying programs (DVDFab, CloneDVD, DVD Cloner, and DVD Rebuilder with various encoders), and the copied DVD results seem to be not too bad, particularly when using DVD Rebuilder.[/QUOTE]
Those programs can’t fixed what came from the Source it has to be re-mastered at the Studio to improve the Film to Media transfer otherwise it would look grainy just like the Film but on media.
[QUOTE=meeshu;2760397]However, there is still some specks/grains and the odd occasional other artefact still showing. I would like to remove, or at least minimize, these artefacts. I’m just a beginner in using these DVD copying programs, so it is not known what are the best programs/encoders and the best settings to use to produce the best quality DVD copy with little or no obvious artefacts showing.[/QUOTE]
Unless they remaster the Original you can only do so much to the video itself.
[QUOTE=meeshu;2760397]Prefer to convert dual layer DVD’s to single layer DVD’s as dual layer DVD’s are a bit difficult to find here, and they are fairly expensive also.[/QUOTE]
As anything not everything can be found everywhere and if you want to go Dual to Single CloneDVD can do that.
[QUOTE=meeshu;2760397]So, what programs and their settings would be suggested to provide the best quality DVD copy with little or no artefacts?[/QUOTE]
I would rather say unless they RE-Master the Film to DVD to improve the quality there is only so much you can do.
