FYI, if you are planning on sending a DVD video for play in a DVD player, Egypt and most other countries in the Eastern Hemisphere run on the PAL format. Its the frame rate and lines of resolution... in the US, we use NTSC.  Videos can be converted, but its kind of a pain in the ass. Just don't send NTSC dvds to egypt and expect them to work. (They would work in a computer, but not a stand alone player).
