I've had that but the other way round. I did have the equipment to transfer a NTSC tape over to UK PAL system though :-) The difference is the fact that NTSC has 425 scanning lines whereas PAL uses 625 (I think I have those figures correct but they are from memory) The new HD format will be universal :-)
NTSC is 525 lines
Where do you get that? Pal is 720x576 and NTSC is 720x480, both in the traditional 4x3 format. widescreen has changed it a little, but I don't see 525 anywhere
There is something called NTSC/525, but in that there are only 480 lines of video, and the rest is used to transmit extra data

You are both correct, I was incorrect. NTSC is indeed 525 lines. Generally 425 is used for the picture with the rest used for other information. PAL is 625. My memory failed me for NTSC; well, it has been 6 years since I did anything in video :-) -- ============================================== I am only human, please forgive me if I make a mistake it is not deliberate. ============================================== Xmas may be over but, PLEASE DON'T drink and drive you'll make it to the next one that way.
