Go to
X:\Users\[Your user name]\Documents\Elder Scrolls Online\live (or liveeu on EU server)
open file UserSettings.txt
find line SkipPregameVideos and change 0 for 1
This make you skip both starting movies and put you on login screen after launching the game.
BUT - i think you still be at risk of freezing at any other movie that start playing in game (like Prophet intro movie)
This looks like some kind of driver problem. You can try to download newest drivers for your graphic card
