I'm using the the above-mentioned card in a Mac Pro. The video input signal is PAL. The problem I have is that the output signal exhibits strange artefacts. Apart from the normal interlacing artefacts, any straight line will look extremely jagged, especially when the video output size is not set to default.
I tried different compression settings and even without compression to no avail.

Can anyone using this card please advise.

. i've just started using my intensity pro (ntsc mode) and haven't noticed anything off... do you have a link to a screen capture of the problem ?

I'm having the same issue

Mac Pro / Blackmagic Intensity Pro with severe Interlacing happening during capture from Output of MacBook Pro (Serato)

It seems Modul8 doesn't discriminate correctly between PAL and NTSC. PAL is odd fields first, while NTSC is even fields first. This would probably explain, why anomad doesn't see my issue.

UPDATE:

Meanwhile I found out, that scaling the video input causes the problem. As long as the size is at default, everything is ok. Once you scale the window the tearing at the edges of objects starts.
