I've been using an old version of this software (v 7.xx) for quite some time. Since I was happy with the quality, I didn't even bother to upgrade to v8.xx. Recently, I tried Rebuilder + CCE, and was amazed with the quality it delivers, specially when doing major compression (lower than 80% original size). Still, RB + CCE takes to much time for me to use it on a regular basis I'm looking for another one click solution since I can no longer use InstantCopy due to a weird error I (and many others) have encountered (Acces violation 00427A93) but that's another story. What software should I try? Although I just enphasized speed, your recomendation should be based on Quality. PS Although Shrink it's a good software, it didn't do it for me when I compared it to IC-7.
I have tried many one click programmes and the best i could recommend would be DVD fab Platinum (express). you can download a free 30 day trial.
