First and foremost, you want an HDTV set. A regular TV, can only display 480i (640x480 interlaced), while an HDTV set can display 480p (640x480 progressive) and 1080i (1920x1080 interlaced). Now, here is what that means. As i said, a regular TV displays 480 horizontal lines. But because a regular TV can only display an interlaced signal, it will only display half of those 480 lines every 1/60th of a second. So at 1/60th of a second it will display line 1, 3, 5, etc, at 2/60th it will display 2, 4, 6, on 3/60th 1, 3 and 5 once again and so on. Now, if you have an HD set, you can use higher resolutions. For DVDs, you will get 480p, meaning that all 480 lines will be displayed every 1/60th of a second, and for HD satellite/cable, you will get 1080i. Now, the important thing to remember is that HD satellite/cable support is very limited at this time. You will get 5 or 6 channels at most. However, as early as next year, the number of HD channels should be a 3-digit number. And a few years down the road, HD will become standart for ALL cable/satellite broadcasts, and you will no longer be able to watch TV with a regular set. So by all means pay extra and get an HDTV. If you want to see the difference between 480i, 480p and 1080i, go down to your local home theater store and tell them to demonstrate on a 36" XBR WEGA. Tell them to play a DVD in 480i, then 480p and then ask them to put on an HD channel on satellite. Your jaw will drop, HD looks stunning.
Second, you also want to get yourself a 16:9 native set. All DVD movies nowdays are 16:9, and if you have a regular 4:3 set, you will get black bars on top and bottom of your screen. On the other hand, you will get gray bars on left and right of the screen while watching 4:3 cable/satellite with a 16:9 set. So it's up to you. What's more important to you: movies or cable? If movies, get a 16:9 set, if cable, get a 4:3.
Finally, if you want both HD and 16:9, it will be tricky getting them both on a tube TV. They do excist. Well, actually, the only one i can think of is this one.
