Re-occuring ceiling cracks

In each of the three bedrooms on the second floor of my 65 year old house have a crack that runs accross the ceiling. Although my walls are plaster I have noticed from the attic that the ceilings appear to be wallboard. I suspect that what is happening is that during the winter the wallboard is shrinking and the crack is forming in between the sheets. Seems to get better in the summer. Last year I used paper tape and patched it up before the winter in one of the bedrooms. Now it looks even worse than the crack alone.

I noticed that someone has suggested using 6" to 8" wide strips of black plastic screening and mud for the ultimate repair. Are there any other suggestions or is there some other underlying problem that is causing these cracks. As well, what is the best compound to use. Should it be the new flexible compound or something really ridgid like durock?
