apologies if this is something that has come up before but i cant find any reference to the problem with my tv... my dvd outputs region1 in either pal 60 or ntsc and i have always had it setup on the ntsc setting with no problem.... however lately it has become noticable that on the tv (hitachi) the top part of the picture is slightly kinked all the way across.. but only for the ntsc pictures! normal tv and PAL dvds are fine?? Anyway if i change the setting on the dvd to output pal60 the picture is fine.. does anyone know why this would be happening?.. and whats the real difference between pal60 and ntsc (apart from no. of lines?). thanks .. a novice!

PAL-60 and NTSC are both 525 lines, 60Hz, so there`s no difference in that respect. The difference is in the way that the colour information is encoded (which only applies to Composite and S-Video, by the way, not RGB). Basically, PAL-60 is a `hybrid` signal intended for use on PAL TVs which can accept a 60Hz input, but can`t decode NTSC colour.
I`m not sure why your picture is `kinked` with NTSC, but it`s possibly a side-effect of Macrovision. A more severe version of Macrovision (called `Color Stripe`) is used with NTSC signals, and your TV may be having an adverse reaction to it.
Anyway, I wouldn`t worry - if it`s fine in PAL-60 mode, just leave it at that.
