Kasper Skårhøj, founder and lead of Typo3, has been doing Typo3 videocasts for a while now. I subscribed to his iTunes feed many moons ago but wanted to point you to his last two episodes. In the second to last videocast, Kasper explains how to build a complete website with Typo3 (268 MB, 1 hour) and in the last videocast, he explains how to translate that website into 3 languages (299 MB, 1 hour).
Have a look at the videocasts to find out how Typo3 deals with custom content types, views, templates and internationalization. Kasper lost me several times, but it is still interesting to see how they approach certain problems. Their concept of page templates and how it blends with the flexible content elements, flexforms, views and the menu system is intriguing.
