All the HD interlaced flavors are UPPER FIRST>
Square have nothing to do here. HDV uses HD pixels.
There is a great article of Chris Poisson about capturing HDV as Prores.
SEARCH in the COW or Google. Everything about HDV have been repeated few millions if times.
[Matthew Chiumento]"Seeing alot of HD video with scan lines and break up in the picture."
I have no idea what you mean by break up, but you're seeing scan lines because you're monitoring on a computer monitor. See my explanation below...
You are looking at interlaced footage on a computer monitor that can't properly display interlaced fields like a proper TV or broadcast monitor. The fields you see on your computer monitor, one is even numbered scan lines, the other odd numbered scan lines, are combined on a TV create a single frame, which has no visible scan lines. On your computer monitor you see the individual fields displayed, not a combined image, i.e. a complete frame.
So, you either have to disregard the interlace when editing on a computer screen or get yourself a setup to display to a TV or broadcast monitor.
Also, keep in mind that if you export for the Web at 50% of the original size or less, that effectively makes the interlace go away. However, if you export for the Web at full size you will have to deinterlace, otherwise the interlace lines will show just as they do now in the FCP canvas.

Down from a certain size (that I do not remember), QT simply do not support Interlaced.
When you downscale the clip, the interlacing goes away.
BUT this automatic de-interlacing normally is VERY VERY bad. You have no control over what it is a very critic operation for your picture.
Always de-interlace by yourself.
I know that David will say that I complicate too much the things.
Have a sunny Sunday, like here.
