I can speak for the 1240. Ive had mine about 3 weeks now and love it. Its lightweight and has a great screen. 1gig ram 1gig HD dvd+- 14 in screen. Circuit city has them with a $50 rebate I think right now.
When I watch DVDs with Intervideo WinDVD, there is a box that allows me to change the screen size to widescreen. It took me a while to find it on the control panel for the program but it works great!
