I hope this is what you need:

When you select a DVD look at the top of your computer. On the second row, directly under "Tools" and "Help", you will see several review sections.

If you touch the tomato symbol you get Rotten Tomatoes movie reviews.

Next to the tomato symbol is the letter E which gives you metacritic reviews.

The next symbol is a star symbol. This gives you the reviews from the invelos community. There are scores posted on the DVDs I checked and may be what you are looking for.

Finally, the next star symbol allows you to contribute reviews for that DVD.

Unless I am confused... those are the scores aren't they?

Metacritic - 56 out of 100
Rotten Tomato  - 65 out of 100
DVD Profier - 4.0 out of 5.0

@Addicted2DVD: The picture I posted was from the release notes, not a screenshot.

Now I found out, what the problem was. I only had small icons activated. These don't show the scores but only the symbols for the sites. When I changed it to big icons, the scores where there.

Screenshots:

Small Icons:


Big Icons:


Unfortunateley the screen size of my laptop is a bit too small for all the big symbols, so I'll have to choose those I need most.

Thanks for your help anyways, I'll try to express myself a bit more clearly in the future
