Jaggies after NTSC conversion

[Neil Goodwill]

I recently bought S2D, and am very pleased with the PAL to NTSC conversion.
I was wondering if there was any way of reducing the jagged edges caused by interlacing on scenes with a large amount of movement. It is only apparent on the NTSC MPEG 2 files, the PAL files have smooth edges. Is it because I am viewing the DVDs on a PAL tv in the UK, and when they are viewed in the States on a proper NTSC tv the jagged edges will not be visible?

I am in the US and have done many PAL to NTSC conversions. Played on my NTSC TV, I have never encountered this problem.

Thank you for your rapid response.
I think it must be because a PAL tv interprets an NTSC signal in a very basic way. Any other opinions on this will be gratefully received. At least I can send off an American couple's wedding DVD with the confidence that they won't complain about jaggies.
The nice things about S2D are the lack of jerkiness after conversion and the speed of operation, unlike Ulead Movie Factory which was extremely jerky and took four times as long to convert!
