You haven't given us much information to work with. What have you done and what message do you get? I haven't set up email on my Playbook, but under the Messages icon it gives you many options to link to various email accounts. You just need to have the correct parameters for your email host. I use my browser to access my email.
If you mean watch a movie...yes..I've downloaded Hollywood movies I've missed and watched them. My family also sends me their videos which I can watch on the PlayBook. You can also watch missed TV shows, You Tube videos and so on.Hope this info helped.
The BlackBerry Playbook can be used as an E-Reader. It comes preloaded with a Kobo Books app, or you can download the Overdrive app for the BlackBerry Playbook from your US library webpage. There are some terrific BlackBerry community support forums (i.e.; CrackBerry, BlackBerry, etc.) where you can research information regarding any BlackBerry products and product capabilities, strengths, and issues.
