Re: [dvd::rip] suggestions for resizing/cropping GUI

[Christian Lambert <clambert@xxxxxxxxxxx>]

Based on my thoughts, I modified the kspread file to add some new
important data.  New version is attached.

- Calculate the target aspect ratio error (helps to make sure
we keep as close as possible to the target aspect ratio).
Target shouldn't be more than 2% off the real aspect ratio

- Make sure the final video size after 2nd clipping and resizing is
a) width dividable by 32  b) height dividable by 16

This is important for most video cards or divx players
to get fullscreen scaling acceleration working right.

Change the original resolution height to 576 if PAL dvd
or 480 for NTSC.

It might be easy to integrate some of those calculation
directly in the GUI and enforce them to make sure people
follow these important rules to get best results.
