Weird green line !!!

Hello everyone.

We purchased two I/Os last week. As Bob Z said it, installing was smooth as s*** from duck's ***. Now I started to work on an anamorphic DVCam project with FCP4 and noticed very ugly green line on top of the picture. And it's same in both I/Os! It's definately made by I/O since it's not in actual clip. We capture it in different edit which doen't have I/O. I wouldn't be so worried if it would only appear in monitor but it goes as well all the way to tape when I'm mastering it anamorphic. With 4:3 this wouldn't be problem since it would be cropped off, but with anamorphic 16:9 I do believe I have a problem.

Then I noticed that if I have 4:3 material which I place into anamorphic sequence there is green line ALSO in right side of the picture. Not way there in right, but excatly there where my 4:3 picture's right side goes. If I move that picture it goes away, but there's still that same green line on top of everything.

So what the heck is going on ??? I thank you all in advantage.
