Answer 1

You can indeed burn moves and shows from the iTunes Store to a data DVD (via Finder or other software) for backup purposes, which is I believe what Byron is asking about (though I can't be sure). You just can't burn them to a video DVD to be played in a standard DVD player.
Well, I'm not sure about that. Having just re-read the terms, it appears that you may re-download content, and that you can burn songs, but this appears to not include videos (unless it is iTunes Plus content):
(iv) You shall be authorized to burn an audio playlist up to seven times.
(v) You shall not be entitled to burn video iTunes Products or ringtone iTunes Products.
(vi) iTunes Plus Products do not contain security technology that limits your usage of such products, and Usage Rules (ii) – (v) do not apply to iTunes Plus Products. You may copy, store, and burn iTunes Plus Products as reasonably necessary for personal, noncommercial use.
Reading further, then there is this:
(ix) Content Rentals
(a) Content rentals are viewable on only one device at a time. You must be connected to the iTunes Service when moving rentals, and you may do so only between your computer and other compatible devices. Content rented using your Apple TV, iPad, iPhone 4, or iPod touch (4th generation) may not be moved. If you move a rental to a compatible device and then use the iTunes Service to restore that device, or choose Settings > Reset > Erase all content and settings on that device, the rental will be permanently deleted.
(b) You have thirty (30) days after downloading a rental to begin viewing. Once you begin viewing, you have twenty-four (24) hours to finish viewing a movie, and forty-eight (48) hours to finish viewing a TV show. Stopping, pausing, or restarting a rental does not extend the available time for viewing.
Some iTunes Products, including but not limited to Content rentals, may be downloaded only once and cannot be replaced if lost for any reason. It is your responsibility not to lose, destroy, or damage iTunes Products once downloaded, and you may wish to back them up.
Even after years of deciphering contracts and the sometimes rather complex content, I find this a bit confusing and I'd be checking with Apple to make sure I'm not doing anything I shouldn't be.
