I eagerly awaited the release of version 1.1.1 with the 1:1 copying. I only want to use this feature for backing up episodal DVD's (Sex and the City, Sopranos, Band of Brothers, Star Trek TNG, etc.)...
I was a little disappointed that we couldn't select which audio streams and the amount of compression per title, but I'm sure that's coming in future versions. Rene did warn that image quality on 1:1 backups would be worse than movie only... here's a comparison I did with Disc 1 of The Sopranos Season 1. The first image is the original from the DVD and the second is after DVD2One processing in full disc mode. Since there are no settings selection, everything was left at default with the final size as 4.37GB.
Captures done with PowerDVD 3.0.
DVD2One in Full Disc Mode:
The original Sopranos disc was 7.3 GB, so there was a 23% compression. Obviously this will have some effect and you can see it above. I believe that the 1:1 feature is not usable at this time unless the original is around 5 - 5.5 GB or so... otherwise the quality is not very acceptable. I only say this because I have a 65" HDTV and everything is magnified.
When we have the option to select the audio streams we want and the compression amount per title, the result should be better.
Curiously, when I backup long movies (Lord of the Rings: Fellowship of the Rings) in movie-only mode, the quality was very good with few pixelation and was very watchable even on a large screen... that probably have a little to do with the original movie quality as well - it's much better than DVD sets of TV sitcoms.
Those are my observations... when I have a little time, I'll process the same disc using the VOBEdit, IfoEdit, etc. route to keep just the episodes and no menus or extras and see how that look. I'll post an image as well.
