I still have these 2 programs on 2 different notebooks and thought that I should post this. First 1 click from the reading that I am doing is capable of compressing a dvd to 4.75 which I do not see in my exisiting Clone DVD. What I was wondering is if this new Pro version of 1 Click requires the use of Any DVD, as the way I read it... or I may have understood it is that it decrypts???? Since I already have a version of 1 click there is a special on the Pro version for $39 to get this program. I am pondering this since I don't seem to see the compression feature in Clone DVD which I use with Any DVD. Uusally I end up using Shrink and Nero to burn along with Any DVD. I would appreciate experienced comments, thankyou. I should say that I have 3 notebooks, one I use Shrink/Nero/Any DVD, the other with 1 Click/Any DVD and the third Clone DVD/Any DVD. But I am finding more and more of my backups need compression and it always seems to be when I am working on my latest notebook that has 1 click/any dvd and that is why I am wondering if it is a reliable program (Pro) with Any DVD and does the compression. I really would appreciate experienced end users comments as everyone here is so helpful. Thankyou.
