Capturing PAL DV

Hi,

I'm attempting to capture from a PAL DV camera using Movie Maker, in the
preview I see my video but it is completly pixelated like a mosaic. I've
tried some other freeware capture software packages but they produce similar
results, however they all report that the input souce is NTSC, and I'm unable
to overide this.

Has anyone else managed to capture PAL DV?

Thanks in advance.

James
