I have been using the previous versions of the products for a while now. I upgraded to version 3 and have tried it and I like the new interface a lot. also, I like the fact that it is clearly indicated that 4450 MB is the recommanded size. If you make any change to this value, it is good to be able to come back to the recommended size. As I said in a previous posting, the product is way ahead of Popcorn, except if you do not need compression. Then Popcorn is faster doing everything in one step instead of two with MTR (preparing the data and then burning it with Toast or something else).
I like being able to remove useless language, dir comments and other stuff I do not need to make the image smaller. Anyway, I highly recommend the product.
