I had my yard marked for utilities before digging for new landscaping(trees, etc). Unfortunately, the cable TV line runs diagonal across my entire back yard. I was planning on putting a 3" diameter tree right where the line runs a few feet from each side of my fence. Is it my responsibility to pay for this relocation, who does it, and any ideas of cost? I am located in the US(Minnesota).
This seemed more like a GC question and less like a landscaping question so I asked here over the gardening SE site.

Like Chris says, you'll likely have to pay for this. If the line had become damaged through no fault of your own, they would pay to run a new line, and at that point you might get them to run it a different way.
That said, cable lines tend to be buried fairly shallow. You can dig it up yourself and rebury it a short distance away. Just be careful when digging it up since they are also easy to damage and they'd likely charge you for the repair. And when you rebury the line, try to get it deep enough so it can't be hit with an aerator or other routine yard maintenance.
