Strobe effect is showing when "filming" in progressive mode

Hello.

I am filming one little thing in progressive mode (with ex-1) and I'm having terrible strobe effect on my footages. I have shutter set to off so I guess it uses shutter 1/50 when I'm having 720p25 mode. I also need to use slow motion in 60p so the shutter should be something like 1/60 or so? It almost looks like playing interlaced material on a tv with wrong fields if you know what I mean.
I don't really know if it just my eyes that sees the terrible effect but if you would like to see, here is a examples mov where I have filmed a newspaper. The first is a bit faster than the second one but on the paper edges you can see the effect.

Is there something that I'm missing here or should the picture be like that?

Thanks, Mikko

Looks fine to me playing on my Apple Cinema Display.
You don't say what you're looking at it on.
When one "sees" something one has to mention where one is looking and device it is being played from.

That's right! I just came from downstairs where we have Apple Cinema displays also and it was way better than with our Dell displays. So it must be it then. I need to ask new monitor. Thanks.

BTW this also holds true with HDTVs. Some handle 24p better than others. Some of the thorough consumer HDTV reviews test for that.
