please take the time to read whole post if you can
quality suffers when using either InstantCopy or DVD2One period regardless whether you can see it or not and whether your setup cost £1 or £1,000,000!
it also suffers less with InstantCopy than it does with DVD2One if both copies compress exactly the same source and have the same output size
though the Quality/Speed ratio between the 2 is more likely to be a little more in DVD2One's favour
but regardless of which you use, as soon as even one bit of information is taken away from original then it will never be as good as the original, if you can see it or not!
if the movie that you are wanting to keep (ie video/audio/extras etc) is bigger than 4.37Gb the more the quality will suffer the more the original filesize is over 4.37Gb
it firstly affects dark areas of the screen,large areas of the same colour and fast moving scenes
try compressing any movie longer than 2 hours with all the soundtracks (especially DTS) and then tell me you can't see the difference
if you tell me you still can't see the difference, I seriously recommend you goto Specsavers!
my 2nd point is that it's beyond belief how people can keep on saying that I have a HUGE TV with top of range BLAH BLAH BLAH cos if anything this should show the quality loss even more as your originals should be amazing so the comparision should be greater and also more obvious due to the large screen!!!
The overall quality of your playback for your particular system can only be as good as the source of the information it is getting. Your system isn't making the copy better, if you think about it's more likely to be showing the original poorer!, you can make an original suffer more by using inferior cables, components etc
as mentioned somewhere else about stripping a car, here is a little scenario
if you have a brand new Porsche that cost's £60K and only have a budget of £43.7K (4.37GB), so what you do is strip the car of performance bits so it only costs £43.7K
is that car still the same as the original and will it perform in the same way?
now tell what would happen if you put yourself (poor component) in that car to drive around a racetrack, would you go round at the same speed and perform in the same way as you would in the original car?
now take that same stripped car and stick Michael Schumacher (a top quality component) in it and he would probably go round faster than yourself in the stripped car and the original car but STILL not as fast as he would go in the original £60K car
for example, in the stripped car you went round in 300 seconds, the original 240 seconds, Schumacher in stripped done it in 200 and in the original 160
now for the maths, the ratio of your original to stripped is 4/5 and shumacher's is also 4/5, so the performance drop is the same yet Schumacher went around faster, basically the stripped car has suffered a 20% performance loss compared to the original (copy DVD to original DVD)
now my whole point is if you relate this to having the best TV/DVD player and leads in the world (Schumacher) and played an original DVD (60K Porsche) in it and gave it's quality a rating of 1000 (160 seconds)
then played that same original DVD in Joe Blogg's average setup you would get a quality rating of 667
now play the copy DVD in the world's best setup and you will get a rating of 800 (20% decrease from original)
and finally play the copy in Joe Blogg's setup and you will get 533
now compare the difference between Joe Blogg's original score and copy score (134), it's smaller than the difference between Schumachers which is 200, so Schumacher suffers MORE performance loss but still has a better performance than Joe Bloggs with the copy!
that is why people probably state that their better setups have good quality copies, but overall they are suffering more quality loss!
I might be wrong but it would be nice to find out why
don't get me wrong both pieces of software are absolutelty great, it's just I cannot understand some people's opinions of them and their performance and also my setup is better than your setup etc
InstantCopy cannot do all the things DVD2One can do and vice versa, the choice is yours as what will suite you best if you wish not to purchase both
but at the end of the day quality is lost either way, the bigger the original file, the more noticable it will be
cheers and thanks for reading and feel free to shoot me down :D
