TV guy is correct, except in interlaced you get one *frame* every 1/30 sec, one *field* every 1/60 sec. A frame is a complete picture (all the lines), a field is half-a-picture (every other line). 1/30 sec frame rate is NTSC/ATSC, not PAL which is 1/25 sec. (To be techincally accurate NTSC/ATSC has a 1/29.97 sec frame rate.) The concept is the same for both; however, 1080i and 1080p are ATSC (high definition) specs.

1080i = Interlaced: Your TV receives two fields of 1920x540 every 60-th of a second (or every 1/30-th of a sec. you get one filed)
1080p = progresive. Your TV receives one 1920x1080 frame every 1/60-th of a sec.

interlaced and progressive scan
interlaced reduces your vertical resolution but offers smoother motion
HD DVD movies shows best in 1080p24 (or 1080p25 or 1080p30 if your TV cant handle 24 frames per second)
broadcast HD television is currently in 1080i25 or 1080i30 but will move to 1080p50 or 180p60 in the future
