A while ago I had used Instant Copy to do a full backup of Spy Kids 2. It took hours and the default settings made the resulting image too large so I had to do it all over again with some more compression. The result was not very good at all with tons of macro blocking and artifacts.
I had did a movie-only backup of Spy Kids 2 with older DVD2One and the quality is great.
Next I did one with DVD95Copy 1.3 set to Repack evenly. It took over 90 minutes and was 4.37GB (slightly too large to fit on DVDR). so I did again with extras compressed at 30% and then it fit. The movie quality had small amount of artifacts here and there but nothing distracting and was perfectly watchable. The menu intro and extras had noticeable artifacts. Now I do not fully understand what that setting does, but maybe if I set it a bit higher it would give better quality and still fit?
I then tried DVD2One 1.1.1. Since it has no option to compress extras at a lower rate, I selected the entire movie. I presume it gives equal compression to everything. I was surprised that it only took 30 minutes to do. The result was 4.36GB so it fit perfect on DVDR. The quality of the main movie was on par with DVD95Copy (even though the compression was higher), and the extras were better too because were compressed less.
I read elsewhere that DVD2One 1.1.1 has problems predicting the size as slightly too large - well at least one can change it. Since it is so quick you can encode the movie twice, presuming the first time is too large, in quicker time than DVD95Copy does its one.
I also noticed that if I play the DVD95Copy backup in my Xbox, the scene selection crashes if I try to right-arrow to the next page. With DVD2One it does not crash. On my Toshiba 5109 both are fine and do not crash. I don't know what this means really... maybe DVD2One is more compatible?!? Need more samples to determine for certain.
Spy Kids 2 seems to me a very good test because there are so much extras. I think that most DVDs will give good results with DVD2One. The next thing I will try is my standard test of LEXX S2 V1, which I have done both using IC and DVD95Copy.
I think DVD2One has redeemed itself and is back in the game! Future upgrades may even have more flexibility - who knows!
