ahhh, I missed the PAL/NTSC part of the question.
To get a little technical:
PAL stands for Phase Alternation by Line, and was adopted in 1967. It has 625 horizontal lines making up the vertical resolution. 50 fields are displayed and interlaced per second, making for a 25 frame per second system. An advantage of this system is a more stable and consistent hue (tint). PAL-M is used only in Brazil. It has 525 lines, at 30 frames per second.
The NTSC standard has a fixed vertical resolution of 525 horizontal lines stacked on top of each other, with varying amounts of "lines" making up the horizontal resolution, depending on the electronics and formats involved. There are 59.94 fields displayed per second. A field is a set of even lines, or odd lines. The odd and even fields are displayed sequentially, thus interlacing the full frame. One full frame, therefore, is made of two interlaced fields, and is displayed about every 1/30 of a second.
To make it a little clearer, the resolution and frame rates are different on PAL and NTSC, and both the TV and DVD player would need to be able to display whatever standard you're using. On the bright side, there are places out there that do sell players and tv's that will display both, just let me know and I can give a heads up.
