Good to hear from you. You’ll find a whole bunch of iPad enthusiasts in this Forum who are only too willing to help other iPad owners and to hear of their experiences. Don’t be afraid to post any questions you may have or use the ‘Search’ button near the top of the Forum web page. I usually find I discover one new interesting and useful piece of information about my iPad every day - and often not even what I was looking for!!
Regarding playing those video file formats - no problem....
Go to the app store and check out oPlayer (that's a letter 'O' not the number - I guess they couldn't call it iPlayer!). It plays just about every video format in the Universe...
Hope to hear from you soon with your thoughts about the iPad.
Have fun and enjoy your iPad
