That's correct. Mine was the same way until I added the ati drivers for 3D 
which in turn added the "fglrx" line and then I added the video overlay 
option myself from suggestions on the web.

There is one more thing to do which is check DMA access. Follow Eberhard's 
post for that and between both of our suggestions the choppy video issue will 
go away.
