Option for deep analysis when backing up using DVD Shrink

[mcdddy1]

I am tyring to back up a DVD using DVD Shrink but when I go to back-up under back-up options I cannot select "Perform Deep analysis before backup to improve quality" (ie its not highlited - I cannot check the box. Why is this? What can I do?
Thanks
P.S. I have tried burning without deep analysis but the video quality isn't very good.

hi mcdddy1

2 reasons why the "perform deep analysis" box is greyed out.

1) you have run a deep a deep analysis already and DVD Shrink has saved the analysis results

2) You do not require compression

or...

- you're backing up from your HD.

- you're backing up from your HD.

It doesn't matter if it is of the HD or the DVD itself.

The reply from Mig$y is correct.
