I sure can, and like explained before, our initial tought while developing DVD2one was that we wanted a program ourselves that could make movie only backups of DVD's who nearly fitted on a DVD-R.
Movies who where about 1Gb to big in size, and the goal was to make a engine who could do that under 15 minutes on my machine. Needless to say we where succesfull in that.
But to use DVD2one on very long movies like LOTR or DAS BOOT isn't really a very good idea because the playlength is so long that the available bitrate in the original movie is to low for DVD2one to maintain a certain quality.
Remember DVD2one is a compressor not an encoder like CCE!
But since more and more people are looking for a good solution even for longer movies we deciced to make some changes in the engine.
The first changes where made in the 1.1.x engine (current release) the next change is planned for the 1.2.x engine and will be a more statistics based engine and thereby more accurate in everything.
But we will never reach the quality which CCE could do in multipass encoding, even if we implented multipass encoding (which would be rather useless since our engine isn't based on that system)
CCE is an encoder and analyses every single frame and then builds a completely new data set (i,p,b frame) and DVD2one bases the compression on the already avaible data!
That doesn't mean the quality can't be improved!
But comparing DVD2one with CCE is like comparing an apple with a pear, both fruit yet very different!
