How to Format for Viewing on TV

Please explain in simple terms the process for exporting a FotoMagico file and copying to a DVD that can be viewed on a High Def TV. I want the DVD to be useble just like those I get from NetFlix. Your help will be much appreciated.

More Information: I exported from FotoMagico 4 using the Custom option to output in .mov format. When I play back on my iMac, it looks great, but on my PC laptop and Samsung High Def Smart TV, the .mov file looks greatly overexposed. HELP!
