Is this a bug? [ after reading the source code ... ] Well, the 0.7.x vbi capture code has a number of bugs and races. It is very sensitive to load. Neverless the worst thing that might happen should be missing vbi data or vbi data mixed from two frames. I can't see a code path there it just blocks ... Can you load bttv 0.7.x with bttv_debug=2, try to make it block in vbi read() and check what you have in the kernel log then?
