The PlayBook support mp4 files, iTunes files have a DRM.
You will have to remove that if you them to run on your PlayBook.

The easiest way to get movies is with the video store app on the playbook if you aren't very technical.

There's an app called itunes sync but as previous poster said, you have to pay apple to rove drm first.

I'm not familiar with tiscali email, first thing to try is a reboot of the the playbook.
