Most modern TVs will take both 50HZ and 60HZ (or 25fps/30fps)  over the 
RGB scart cable.  PAL and NTSC are not relly involved, and are only 
shorthand for the resolution and refresh rate. Most DVD players will 
play "NTSC" out of a scart socket in the UK as "PAL60". If you have a 
reasonably modern TV, you can feed it a Modeline that will probably work.

I'm using :
#PAL reduced overscan
ModeLine "720x576 at 25i" 13.5   720 732 795 864  576 579 584 625 interlace 
-hsync -vsync
#NTSC
ModeLine "720x480 at 30i" 13.5   720 736 799 858  480 486 492 525 interlace 
-hsync -vsync

They work well on my Sony Trinitron.
