So a partial answer to my own question – capturing at 1080i, all the information is there, but for some reason QT saves it to show at one quarter size.
By going into movie properties and re-sizing it to 1920 by 1080, I get pretty pictures. Not sure why this happens, but at least it can work – saves me needing to install FCP on my capture laptops.
However, QTPro does not seem to understand 720p – lots of macro blocking on the capture with the blocks in the wrong places – even if I resize the capture.
Anyone else trying this ?
