Shouldn't happen.  Which driver is this?  Maybe it is just the fact
that you have to tune some station before you get any usable data on

That shouldn't happen, the video + vbi streams are not linked in a way
that video frame drops also mean vbi frame drops.  Unless the frame
drops happen due to input bad signal of course ...
