Hi Andy,
I’m checking the settings, but all I can find actually is a little ratio different (after effect 768×576 / premiere 720x 576) but I don’t know if that can be the cause of the problem. Maybe you already get it, but I’m not a well experienced of premier, and its interface changing in the cs5 make me a little disoriented about the settings. As I’ve told you, this time I’m getting the problem after switched to cs5. With cs4 I got the correct export you’ve seen in the initial post.
You can see some pictures attached to this post.
1,2,3 are screenshots of after effect, composition setting and export.



Figure 4 is premiere export setting.

Maybe you see something wrong I cannot understand?
Sorry for all these posts. I’d really like to understand what’s going on
Thanks
F.
